### The case for Small Data compression
-Previous charts provide results applicable to typical files and streams scenarios (several MB). Small data come with different perspectives. The smaller the amount of data to compress, the more difficult it is to achieve any significant compression.
+Previous charts provide results applicable to typical file and stream scenarios (several MB). Small data comes with different perspectives. The smaller the amount of data to compress, the more difficult it is to achieve any significant compression.

-To solve this situation, Zstd offers a __training mode__, which can be used to tune the algorithm for a selected type of data, by providing it with a few samples. The result of the training is stored in a file called "dictionary", which can be loaded before compression and decompression. Using this dictionary, the compression ratio achievable on small data improves dramatically :

These compression gains are achieved while simultaneously providing faster compression and decompression speeds.
-Dictionary work if there is some correlation in a family of small data (there is no _universal dictionary_).
-Hence, deploying one dictionary per type of data will provide the greater benefits. Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm will rely more and more on previously decoded content to compress the rest of the file.

+### Build
+
+Once you have the repository cloned, there are multiple ways provided to build Zstandard.
+
+#### Makefile
+
+If your system is compatible with a standard `make` (or `gmake`) binary generator,
+you can simply run it at the root directory.
+It will generate `zstd` within root directory.
+
+Other available options include :
+- `make install` : create and install zstd binary, library and man page
+- `make test` : create and run `zstd` and test tools on local platform
+
+#### cmake
+
+A `cmake` project generator is provided within `build/cmake`.
+It can generate Makefiles or other build scripts
+to create `zstd` binary, and `libzstd` dynamic and static libraries.
+
+#### Visual (Windows)
+
+Going into `build` directory, you will find additional possibilities :
+- Projects for Visual Studio 2005, 2008 and 2010
+ + VS2010 project is compatible with VS2012, VS2013 and VS2015
+- Automated build scripts for Visual compiler by @KrzysFR , in `build/VS_scripts`,
+ which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.
+
+
### Status
-Zstandard is currently deployed within Facebook. It is used daily to compress and decompress very large amount of data in multiple formats and use cases.
+Zstandard is currently deployed within Facebook. It is used daily to compress and decompress very large amounts of data in multiple formats and use cases.

+# Parallel Zstandard (PZstandard)
+
+Parallel Zstandard is a Pigz-like tool for Zstandard.
+It provides Zstandard format compatible compression and decompression that is able to utilize multiple cores.
+It breaks the input up into equal sized chunks and compresses each chunk independently into a Zstandard frame.
+It then concatenates the frames together to produce the final compressed output.
+Pzstandard will write a 12 byte header for each frame that is a skippable frame in the Zstandard format, which tells PZstandard the size of the next compressed frame.
+PZstandard supports parallel decompression of files compressed with PZstandard.
+When decompressing files compressed with Zstandard, PZstandard does IO in one thread, and decompression in another.
+
+## Usage
+
+PZstandard supports the same command line interface as Zstandard, but also provies the `-p` option to specify the number of threads.
+Dictionary mode is not currently supported.
+
+Basic usage
+
+ pzstd input-file -o output-file -p num-threads -# # Compression
+ pzstd -d input-file -o output-file -p num-threads # Decompression
+
+PZstandard also supports piping and fifo pipes
+
+ cat input-file | pzstd -p num-threads -# -c > /dev/null
+
+For more options
+
+ pzstd --help
+
+PZstandard tries to pick a smart default number of threads if not specified (displayed in `pzstd --help`).
+If this number is not suitable, during compilation you can define `PZSTD_NUM_THREADS` to the number of threads you prefer.
+
+## Benchmarks
+
+As a reference, PZstandard and Pigz were compared on an Intel Core i7 @ 3.1 GHz, each using 4 threads, with the [Silesia compression corpus](http://sun.aei.polsl.pl/~sdeor/index.php?page=silesia).
+
+Compression Speed vs Ratio with 4 Threads | Decompression Speed with 4 Threads
+------------------------------------------|-----------------------------------
+ | 
+
+The test procedure was to run each of the following commands 2 times for each compression level, and take the minimum time.
+
+ time pzstd -# -p 4 -c silesia.tar > silesia.tar.zst
+ time pzstd -d -p 4 -c silesia.tar.zst > /dev/null
+
+ time pigz -# -p 4 -k -c silesia.tar > silesia.tar.gz
+ time pigz -d -p 4 -k -c silesia.tar.gz > /dev/null
+
+PZstandard was tested using compression levels 1-19, and Pigz was tested using compression levels 1-9.
+Pigz cannot do parallel decompression, it simply does each of reading, decompression, and writing on separate threads.
+
+## Tests
+
+Tests require that you have [gtest](https://github.com/google/googletest) installed.
+Modify `GTEST_INC` and `GTEST_LIB` in `test/Makefile` and `utils/test/Makefile` to work for your install of gtest.
+Then run `make test` in the `contrib/pzstd` directory.

+#### The measurement of performace of Zstandard wrapper for zlib
+
+The zstd distribution contains a tool called `zwrapbench` which can measure speed and ratio of zlib, zstd, and the wrapper.
+The benchmark is conducted using given filenames or synthetic data if filenames are not provided.
+The files are read into memory and joined together.
+It makes benchmark more precise as it eliminates I/O overhead.
+Many filenames can be supplied as multiple parameters, parameters with wildcards or names of directories can be used as parameters with the -r option.
+One can select compression levels starting from `-b` and ending with `-e`. The `-i` parameter selects minimal time used for each of tested levels.
+With `-B` option bigger files can be divided into smaller, independently compressed blocks.
+The benchmark tool can be compiled with `make zwrapbench` using [zlibWrapper/Makefile](Makefile).
+
+
+#### Improving speed of streaming compression
+
+During streaming compression the compressor never knows how big is data to compress.
+Zstandard compression can be improved by providing size of source data to the compressor. By default streaming compressor assumes that data is bigger than 256 KB but it can hurt compression speed on smaller data.
+The zstd wrapper provides the `ZWRAP_setPledgedSrcSize()` function that allows to change a pledged source size for a given compression stream.
+The function will change zstd compression parameters what may improve compression speed and/or ratio.
+It should be called just after `deflateInit()`or `deflateReset()` and before `deflate()` or `deflateSetDictionary()`. The function is only helpful when data is compressed in blocks. There will be no change in case of `deflateInit()` or `deflateReset()` immediately followed by `deflate(strm, Z_FINISH)`
+as this case is automatically detected.
+
+
+#### Reusing contexts
+
+The ordinary zlib compression of two files/streams allocates two contexts:
+- for the 1st file calls `deflateInit`, `deflate`, `...`, `deflate`, `defalateEnd`
+- for the 2nd file calls `deflateInit`, `deflate`, `...`, `deflate`, `defalateEnd`
+
+The speed of compression can be improved with reusing a single context with following steps:
+- initialize the context with `deflateInit`
+- for the 1st file call `deflate`, `...`, `deflate`
+- for the 2nd file call `deflateReset`, `deflate`, `...`, `deflate`
+- free the context with `deflateEnd`
+
+To check the difference we made experiments using `zwrapbench -ri6b6` with zstd and zlib compression (both at level 6).
+The input data was decompressed git repository downloaded from https://github.com/git/git/archive/master.zip which contains 2979 files.
+The table below shows that reusing contexts has a minor influence on zlib but it gives improvement for zstd.
+In our example (the last 2 lines) it gives 4% better compression speed and 5% better decompression speed.

#### Compatibility issues
-After enabling zstd compression not all native zlib functions are supported. When calling unsupported methods they print error message and return an error value.

+ data in order to determine how much of that input will compress to
+ nearly the requested output block size. The first pass generates
+ enough deflate blocks to produce output to fill the requested
+ output size plus a specfied excess amount (see the EXCESS define
+ below). The last deflate block may go quite a bit past that, but
+ is discarded. The second pass decompresses and recompresses just
+ the compressed data that fit in the requested plus excess sized
+ buffer. The deflate process is terminated after that amount of
+ input, which is less than the amount consumed on the first pass.
+ The last deflate block of the result will be of a comparable size
+ to the final product, so that the header for that deflate block and
+ the compression ratio for that block will be about the same as in
+ the final product. The third compression pass decompresses the
+ result of the second step, but only the compressed data up to the
+ requested size minus an amount to allow the compressed stream to
+ complete (see the MARGIN define below). That will result in a
+ final compressed stream whose length is less than or equal to the
+ requested size. Assuming sufficient input and a requested size
+ greater than a few hundred bytes, the shortfall will typically be
+ less than ten bytes.
+
+ If the input is short enough that the first compression completes
+ before filling the requested output size, then that compressed
+ stream is return with no recompression.
+
+ EXCESS is chosen to be just greater than the shortfall seen in a
+ two pass approach similar to the above. That shortfall is due to
+ the last deflate block compressing more efficiently with a smaller
+ header on the second pass. EXCESS is set to be large enough so
+ that there is enough uncompressed data for the second pass to fill
+ out the requested size, and small enough so that the final deflate
+ block of the second pass will be close in size to the final deflate
+ block of the third and final pass. MARGIN is chosen to be just
+ large enough to assure that the final compression has enough room
+ to complete in all cases.

#### Bitstream
-All sequences are stored in a single bitstream, read _backward_.
-It is therefore necessary to know the bitstream size,
-which is deducted from compressed block size.
+FSE bitstreams are read in reverse direction than written. In zstd,
+the compressor writes bits forward into a block and the decompressor
+must read the bitstream _backwards_.
+
+To find the start of the bitstream it is therefore necessary to
+know the offset of the last byte of the block which can be found
+by counting `Block_Size` bytes after the block header.
+
+After writing the last bit containing information, the compressor
+writes a single `1`-bit and then fills the byte with 0-7 `0` bits of
+padding. The last byte of the compressed bitstream cannot be `0` for
+that reason.
-The last useful bit of the stream is followed by an end-bit-flag.
-Highest bit of last byte is this flag.
-It does not belong to the useful part of the bitstream.
-Therefore, last byte has 0-7 useful bits.
-Note that it also means that last byte cannot be `0`.
+When decompressing, the last byte containing the padding is the first
+byte to read. The decompressor needs to skip 0-7 initial `0`-bits and
+the first `1`-bit it occurs. Afterwards, the useful part of the bitstream

+
+This appendix contains FSE decoding tables for the predefined literal length, match length, and offset
+codes. The tables have been constructed using the algorithm as given above in the

+to crosscheck that an implementation implements the decoding table generation algorithm correctly.
