I have installed jira 4.4.3 on linux server with 4GB RAM. I use external mysql database. Database is clean, jira wasn't in usage yet. I noticed that it runs very slow. When I have checked memory consumption with ps aux command I saw jira 48% of memory consumption (about 1.8 GB) (CPU load is about 2-3%). What it can be and how I can debug this problem?
It is interesting, that JVM_MAXIMUM_MEMORY is set to 768MB.
