Zitat von Tim Delaney <timothy.c.delaney at gmail.com>:

To be clear - I'm not suggesting Cython become part of the required build toolchain. But if the Cython-compiled extensions prove to be significantly faster I'm thinking maybe it could become a semi-supported option (e.g. a HOWTO with the caveat "it worked on this particular system"). This should compare to zipping the standard library, which has been a supported configuration for a long time, and also avoids many stat calls.

Interestingly, I just did a quick test of this: This is on my Windows 7 PC, running under Powershell. D:\Apps\Python33 is a standard installation, whereas D:\Dev\P33 has a zipped stdlib:

PS 22:02 D:\Data

foreach ($i in 1..10) { measure-command { D:\Apps\Python33\python.exe -c "raise SystemExit" } | % { $.TotalSeconds } } 0.0737877 0.1014695 0.0950326 0.0910734 0.0689548 0.084994 0.0772204 0.0958197 0.0696385 0.0806066 PS 22:03 D:\Data foreach ($i in 1..10) { measure-command { D:\Dev\P33\python.exe -c "raise SystemExit" } | % { $.TotalSeconds } } 0.1922151 0.1879894 0.2455766 0.2842425 0.1937161 0.2168928 0.2441508 0.1860206 0.1866409 0.1897004

Looks like the normal configuration is over twice as fast as the zipped one...

Paul.
