As mentioned in http://issues.bestpractical.com/Ticket/Display.html?id=17673 If you make enough requests, slowness due to css squishing will go away. Your first N requests after an apache restart will pay the startup cost. There are scripts on the ticket for demonstrating this. jsmin just makes the css squishing much faster reducing the startup penalty. -kevin pgpvX4PSoUKXA.pgp Description: PGP signature 2011 Training: http://bestpractical.com/services/training.html

Re: [rt-users] Tuning RT4
Hi, For every web request you should see a profile dumped to stderr. If it's a standalone server then it's dumped into console. If it's apache then into apache's error log.

Re: [rt-users] Tuning RT4
I can't speak for the dev team, but I have noticed a distinct trend: Apache+mod_perl is very slow with RT4.0. Lighttpd+FCGI is fast with RT4.0. Standalone PSGI is really fast with RT4.0 (but not very scalable unless you know what you're doing). I haven't tested Apache with anything other than mod_perl, so I don't know if it's Apache-specific or mod_perl-specific. Most of the speed problems I've seen posted here are with RHEL/CentOS/SL stock httpd mod_perl installs, so it's also possible the problem is OS-specific.

Re: [rt-users] Tuning RT4
Hello... I am a brand new RT user. This is my first post. We are network people and dont know much about apache and web server tuning and so forth. (learning fast). But, the first trial install of RT that I made using Rt 3.8 using the Ubuntu packages on an Ubuntu 10.04 virtual machine with 1gb ram was super fast. Having reviewed RT on that platform, I decided to commit to RT, and made an install of RT 4.0.1 on a fresh but identical Ubuntu 10.04 virtual machine, using Apache2 and mod_perl. The RT 4.0.1 is very sluggish compared to the 3.8 version. My RT installs have only the general queue and 5 or 10 tickets as I am just in the trial stage. The web UI is Very slow in 4.0.1. The php.info and other apache status pages, and webmin that I have running on this machine are superfast, so I point to RT as being the culprit. Can anyone help me troubleshoot this?

In RT4 and 3 as well you can use the following option in the config to set mason's properties: Set(@MasonParameters, preamble = 'my $p = MasonX::Profiler-new($m, $r);', ); Arguments are described in http://search.cpan.org/dist/HTML-Mason/lib/HTML/Mason/Params.pod, in RT config you should use perl name of the options. Want to note that: * RT uses static source if DevelMode is not enabled * Preloading may help, but not everything can be preloaded * Buffer preallocation may has less or no effect on RT4 Other options are either dangerouse or useless for admins. -- Best regards, Ruslan. 2011 Training: http://bestpractical.com/services/training.html
