Right. I went back at my install notes and I tried installing TC in
standalone WSGI mode a few months ago. I made it part of the way (I'm
on windows, so I need to tweak a few lines in a few TC files ...), so
given I didn't get it to work I reverted to CGI. Had I known about the
speed difference, I'd have worked harder at the WSGI implementation. I
think it should be stressed in the docs that the cgi implementation is
slower. For noobs like me at least.
I didn't find mod_python in the list of so's of my windows Apache, so do
you suggest I get mod_python to work or the WSGI standalone mode ? I
understand the latter means another server on another port, but is there
a speed advantage using Paste over Apache ?
Thanx a lot for your timely comment. I was about to abandon TC ...
