Alexandre Vassalotti <[EMAIL PROTECTED]> added the comment: The solution is to add a read buffer to Unpickler (Pickler already has a write buffer, so that why it is unaffected). I believe this would mitigate much of the (quite large) Python function call overhead.
cPickle has a performance hack to make it uses cStringIO and PyFile directly (via C function calls). In Python 3, the hack was removed since cStringIO.h and fileobject.h aren't public anymore. This explains the 0.02s deviation you are getting for dump speed. ---------- nosy: +alexandre.vassalotti _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3873> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
