since a few weeks I have more and more performance issues with request tracker.
- VMware virtual machine
- 8 CPU cores
- 32GB memory
- very fast SSD/SAS storage
- ubuntu 14.04
- postgres 9.3.21
- apache 2.4.7
- request tracker 4.4.0
we have about 610000 tickets and about 100 active users.
Yesterday I incresed the virtual machine from 6 cores / 24GB memory to 8 cores / 32GB memory without making it better.
CPU-load average is about 2,50 to 3,50
memory usage is (in the moment) at about 12GB, swap is empty
can you help me troubleshooting this issue?
