[Pbuilder-maint] benchmarking cowbuilder

[Junichi Uekawa]

Hi,

I've done some basic benchmarking on pbuilder/cowbuilder.  I see that
it is quite advantageous, considering that pbuilder login is so much
quicker.

I'm currently thinking about adding this utility into cowdancer
package.



pbuilder update time measurement on iBook G4 1GHz:

cowbuilder:
real    0m16.792s
user    0m4.395s
sys     0m3.568s

pbuilder:
real    2m30.573s
user    0m38.957s
sys     0m6.523s

pbuilder build time with network down (no package install) on iBook G4
1GHz:

cowbuilder:
real    0m18.694s
user    0m7.899s
sys     0m2.872s

pbuilder:
real    1m20.407s
user    0m9.688s
sys     0m4.142s

with network up: (building pbuilder package)
cowbuilder:
real    1m26.027s
user    0m21.582s
sys     0m7.377s

pbuilder:
real    2m57.126s
user    0m22.255s
sys     0m7.961s


pbuilder login
cowbuilder:
real    0m4.488s
user    0m1.039s
sys     0m1.393s

pbuilder:
real    1m20.058s
user    0m4.526s
sys     0m3.689s
