             Summary: wiki.o.o optimization
                 Key: INFRA-5766
                 URL: https://issues.apache.org/jira/browse/INFRA-5766
             Project: Infrastructure
          Issue Type: Task
      Security Level: public (Regular issues)
          Components: Analysis
         Environment: httpd, ats, mysql, memcached on ubuntu 12.04
            Reporter: jan iversen
            Priority: Minor


In order to complete the wiki.o.o installation on wiki2-vm, the following optimization step should be carried out:

- Limit ATS memory/swap usage
- Limit PHP/httpd swap usage
- Analyze how many httpd threads is needed
- align number of parallel httpd threads, php jobs, concurrent mysql sessions
- convert mysql tables to innodb (analyze done earlier thumbs/janIV)
- increase innodb buffering
- reduce myisam buffering
- run performancetest on mysql, after at least 24 hours of  stable environment

The list might not be complete, and some of the items needs to carried out repeately.
