Please explain how to reproduce your benchmark. Maybe write a shell script?

Hello,

1).I was going through the code of python pickle to search any optimization possibility.But the only thing that I found very alarming was again the import time(I tried with lazy-import but it didn't helped much.) I found py3 to be ~45 times slower on* initial imports(very raw measure..using "time." ) *as compared to py2 on an usual example. py3-> ./python -c ' favoritecolor = { "lion": "yellow", "kitty": "red" } pickle.dump( favoritecolor, open( "save.p", "wb" ) )' 0.009715557098388672(time taken to do initial imports...measured using time.time() ) py2-> ./python -c ' favoritecolor = { "lion": "yellow", "kitty": "red" } pickle.dump( favoritecolor, open( "save.p", "wb" ) )' 0.000236034393311(time taken to do initial imports...measured using time.time() ) Do you have any thought/ideas on improving this?

Thank You.
