Hello, I've just started using mod_python, I wrote my own handler and some modules. After a bit of work i saw what I believed was bad performance, and I started profiling. What I've found is this: ab -n 100 http://localhost/not_found.html Trying to fetch non-existant file, that is, just apache: 623 req/sec) ab -n 100 http://localhost/python_bare.py It's only contents are "def handler(req): return": 324 req/sec ab -n 100 http://localhost/python_session.py Contents of python_session.py --------------- def handler(req): from mod_python import Session req.sess = Session.Session(req) req.sess.save() return --------------- 8 req/sec !!!! As we can't use MemorySession on Linux (Linux is multiprocess, right?) what are the possible alternatives? Would a custom FileSession ala PHP be faster? I found an old post from 2001 where some people recommended using a custom Session Server but I don't know if this recommendation still holds. Server: Hardware: CPU 1ghz, 1Gb RAM 133Mhz, 7200 rpm ATA hdd and negligible load Software: Debian stable, apache 2.0.52 prefork, mod_python 3.1, python 2.4 Thanks in advance for any advice. PD: Just for the record, a similar php_bare test with "function test() { return; } test();" and in the same conditions brought 316 req/sec. -- Juan Alonso http://gamersmafia.com | http://laflecha.net
