This is my first post. We are network people and dont know much about apache and web server tuning and so forth. (learning fast).<br><br>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.<br><br>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.<br><br>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.<br><br>The web UI is Very slow in 4.0.1.<br><br>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.<br><br>Can anyone help me troubleshoot this?<br><br>Thanks,<br><br>Alex<br><br><u>Techy details about my install:</u><br><br><strong>OS: </strong>Ubuntu 10.04 vsphere 4.1 esxi virtual machine, 1gb ram, 1cpu, 20gb disk thin provisioned.<br><span style="font-weight: bold;">Apache: </span>Server Version: Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.9 with
