Hi, You do not mention if you use MySQL. For our setup it was not apache that was the bottleneck, rather MySQL. There were a few things we did to speed up OTRS dramatically: 1) Follow through all the steps mentioned in the OTRS support module 2) Restart all services (MySQL, Apache and OTRS) 3) Next optimize all tables in your MySQL database: We have a script “optimizetable” with the following contents: #!/bin/bash for db in $(echo "SHOW DATABASES;" | mysql -u$1 --password=$2 | grep -v -e "Database" -e "information_schema") do TABLES=$(echo "USE $db; SHOW TABLES;" | mysql -u$1 --password=$2 | grep -v Tables_in_) echo "Switching to database $db" for table in $TABLES do echo -n " * Optimizing table $table ... " echo "USE $db; OPTIMIZE TABLE $table" | mysql -u$1 --password=$2 >/dev/null echo "done." done done This is called using the following call: cd /root/Desktop ./optimizetable root EnterPasswordHere 4) Another useful tool I found was “mysqltuner.pl”: http://mysqltuner.pl/mysqltuner.pl . Google for the name, and download the perl script to your OTRS MySQL server. In essence it reads the log files of MySQL and makes recommendations how to improve the performance of MySQL. Your MySQL needs to be running quite some time in production for the recommendations to be accurate. We normally run the script, make appropriate modifications to the MySQL config, restart MySQL, reorganize all tables, then restart all services (OTRS, Apache, MySQL) and then let the server run in production for one or two weeks. Then we follow the same steps as above. After two weeks in normal production you have enough info in the log for the tool to make decent recommendations. The perl script is called using: cd /root/Desktop perl mysqltuner.pl --user root --pass EnterPasswordHere The above steps dramatically improved the performance of OTRS. Hope this helps.

Betreff: [otrs] Otrs with lighttpd + fastcgi Hello, has anyone tried using lighttpd + fascgi instead of apache + mod_perl? My otrs is very slow, so I was wondering if this could help Thanks
