We're up to 30 logbooks, 3.2GB data total and Elog damen has now become slow. Performance stats show 100%CPU on startup then reduces. Searches and general UI activity is slow. It runs on a VM with 4GB memory allocated. Up to 15 concurrent users.

Trimming and archiving some data files may help but I gather overall this is underpowered hardware in this instance so what is recommended system requirements for a config like this?
