Hi,
I recently migrated from mod_fastcgi to mod_fcgid and experienced
enormous
performance boost.
My current settings is as follows -
FcgidMaxProcesses 100
FcgidMaxProcessesPerClass 50
FcgidFixPathInfo 1
FcgidPassHeader HTTP_AUTHORIZATION
FcgidMaxRequestsPerProcess 10000
Since this is PHP, make sure you sync PHP's child exit strategy with
mod_fcgid's max-requests-per-process.
See "Special PHP considerations" at
http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html for discussion of
a couple of issues.
FcgidOutputBufferSize 1048576
FcgidProcessLifeTime 1800
FcgidMinProcessesPerClass 2
Main use is for PHP applications, but in future may add some languages.
Server config -
Fedora 12, 500 MB RAM, Pentium 2 Ghz
PHP applications are cached using Xcache, and will normally use
PostgreSQL.
Yeah I've synced that by setting the relevant PHP_FCGI_* environment
variables.
But Xcache doesn't work with mod_fcgid. Any solutions for that ? Can I use
any alternatives to Xcache to cache the compiled code of the PHP script ?
Aren't APC and Xcache similar with respect to mod_fcgid, in that the
cache will be utilized for repeated execution by the same PHP process,
such that the cache is still useful as long as the PHP process spawned
by mod_fcgid remains active for as long as possible?
(mod_fcgid's mapping of requests to idle processes it has spawned
negates the use of a single such cache for multiple concurrent
requests.)

Yeah true. I think I don't need it after you said this. :)
Is even memcached the same wrt mod_fcgid, apc, xcache ?
