My current settings is as follows - FcgidMaxProcesses 100 FcgidMaxProcessesPerClass 50 FcgidFixPathInfo 1 FcgidPassHeader HTTP_AUTHORIZATION FcgidMaxRequestsPerProcess 10000Since 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.) --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.

I think I don't need it after you said this. :) Is even memcached the same wrt mod_fcgid, apc, xcache ?I found that its not the same and it can't be used as a cache for compiled scripts. mod_fcgid really is infinite times better than mod_fastcgi.For PHP opcode caching, which relies on access to a shared memory cache via the PHP FastCGI process management, mod_fcgid is at a big disadvantage to mod_fcgid: mod_fastcgi can send multiple simultaneous requests to those PHP-managed processes but mod_fcgid can't; thus, the cache won't be as well utilized with mod_fcgid. I have read numerous statements that mod_fcgid is faster than mod_fastcgi, but I don't know precisely why (or when), or if each is optimally configured when compared to the other. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.

I configured mod_fcgid with almost the same parameters as mod_fastcgi and experienced a lot of performance boost.
