| there's still the suggestion of using turck mmcache. the last release is from 11/2003! is that recommendation valid? are there better alternatives? what about eaccelerator?
| | Performance - G, Apr 11, very good, re-use, |
| | | related and useful is Performance_FAQ |
| eAccelerator does seem by consensus to be the way to go, but though there's a working beta there appear to be issues with its stability and performance, especially with PHP5 (e.g. breaks the -GRACEFUL command in apachectl). It's flagged as unstable in most repositories - the message on the forums appears to be wait around a little! Rory Allford

| I have no idea how to interpret the output of this :-( What value:
| |
| #ps -ylC httpd --sort:rss

| For me "#ps -ylC httpd --sort:rss" returned no results, however "#ps -ylC apache2 --sort:rss" does return results.
| |
| | |
| So for my box running the above command gives me:
| |
| | |
| root@intranet:~# ps -ylC apache2 --sort:rss

| However I am struggling to work out which value I need to be looking at and how it relates to the expected 10 mb per process! My sums are giving me an average of between 127 and 80 mb depending on if I use rss or sz to take my average. This is well over the suggested 10 mb!

| == Linux Performance Team? Outdated ==
| |
| | |
| The Linux Performance Team website was last updated in 2004.
| |
| Is this still even relevant at this point? (6 years later represents MASSIVE jumps in computing spaces)

| Hi,
| |
| | |
| on https://docs.moodle.org/en/Performance#Apache_performance someone wrote:
| |
| > So, if your site is SSL-enabled, and you use Apache, you should set the KeepAliveTimeout to at least 60 seconds.
| |
| | |
| I guess it is fixed in new Apache-Versions by adding an IE-Hack on mod_ssl:
| |
| http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html#msie
| |
| | |
| dm
| |
| | |
| Confirmed, mod_ssl under Ubuntu 10.04 LTS is pre-configured with this workaround. Furthermore, there's a note in the config file saying that IE7+ no longer has this problem, so I'm going to remove this advice.

| == Apache Lounge ==
| |
| | |
| Under https://docs.moodle.org/en/Performance#Apache_performance there is, "* If you are using Apache on a Windows server, use the build from Apache Lounge which is reported to have performance and stability improvements compared to the official Apache download. Note that this is an unofficial build, so may not keep up with official releases."
| |
| | |
| I have never used it, but http://www.apachelounge.com/download/ says "Apache 2.2 win32 binary: The windows binary is build with original sources from ASF ( http://httpd.apache.org ) and contains the latest patches." That should be mentioned. -- Visvanath 7. May 2010 18:16 MEST
