If you are using WebSphere and Maximo 5 or above, you can improve your performance by changing a few parameters. This performance improvement is memory related, so if you’ve noticed that your Maximo server is starved of memory after prolonged use, this change is certainly helpful.
The basic idea is to change this parameter value in IBM WebSphere to 10000.
There is a trade off with changing this parameter though. By lowering the timeout, you increase the CPU utilization. [IBM Support]
