More benchmarks: pyxmlrpc (http://sourceforge.net/projects/py-xmlrpc/) is a c implementation that is roughly 2 times faster than xmlrpclib on small inputs. Here are some numbers on linux running sage 2.10.1: pyxmlrpc: sage: %timeit ("c.execute('add', [2r, 3r])") 1000000 loops, best of 3: 65.8 ns per loop sage: timeit c.execute('add', [2r, 3r]) 1000 loops, best of 3: 1.46 ms per loop xmlrpclib: sage: %timeit ("s.add([2r,3r])") 1000000 loops, best of 3: 158 ns per loop sage: timeit s.add([2r,3r]) 100 loops, best of 3: 1.94 ms per loop overall: sage: time for _ in range(10^3): gp.eval('2+3') CPU times: user 0.34 s, sys: 0.10 s, total: 0.45 s Wall time: 0.82 sage: time for _ in range(10^3): c.execute('add', [2r, 3r]) CPU times: user 0.08 s, sys: 0.02 s, total: 0.10 s Wall time: 1.66 sage: time for _ in range(10^3): s.add([2r,3r]) CPU times: user 0.99 s, sys: 0.38 s, total: 1.37 s Wall time: 2.51 Note: The pyxmlrpc is currently unmaintained (last realease was in 2004) and needs to be patched against 2.5 (there's a fix at the bottom of http://sourceforge.net/tracker/index.php?func=detail&aid=1734819&group_id=23992&atid=380301). didier --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
