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 '
favorite_color = { "lion": "yellow", "kitty": "red" }
pickle.dump( favorite_color, open( "save.p", "wb" ) )'
0.009715557098388672(time taken to do initial imports...measured using
*time.time()* )

py2->
./python -c '
favorite_color = { "lion": "yellow", "kitty": "red" }
pickle.dump( favorite_color, 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.
