There's a big difference in the number of requests per second, four times more in the Windows machine. Anyone knows why? Does it mean that Zope running in Windows is better than in Linux?

When you think that this is the reality in the web, then yes. But, if you think of the following scenario: 1 file accessed: windows very fast linux normal speed 1 file accessed by 10 peoples at the same time: windows very fast linux normal speed 1 file accessed by 100 peoples at the same time: windows fast linux normal speed 100 files accessed by 1000 peoples at the same time: windows, stalled linux, umm, normal speed A windows web server is nothing but a bad emulation of a Unix system. -goe- _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
