I installed Cisco Prime LMS using the small server (up to 500 devices) virtual appliance OVA. It was set up with the standard settings for the OVA - 2 vCPUs, 4 Gb RAM, and 256Gb disk. Web interface is very slow. I have less than 200 devices. What should I tune/check for to improve performance, hopefully without having to dedicate more compute resources? Could this be an issue with my browser or version of java instead of the server?
