Da_Blitz <pypy at pocketnix.org> added the comment:

running the benchmark through strace for the zipfile case shows pypy doing alot
of single byte reads and python doing reads of 10240 bytes. this would explain
why manually forcing the buffer size speeds up the subprocess module

taking a look into the subprocess module now to see what i can find
