We are currently using the UMP 2.1 in a lab environment, but are having some problems with the speed of the UMP. Everything seems slow - loading the portlets takes about 10 seconds, and then 20 seconds later the data for a given portlet (including the alarm console!) finally loads.
Currently, our implementation consists of 4 VMs on two ESXi Hypervisors - the primary hub and the DB on one hypervisor, and the UMP and the secondary hub on another. These hypervisors are not that loaded, either. I have given the following mem/cpu parameters to the VMs.
MySQL DB server - 4CPUs, 4GB of memory
UMP - 1 CPU, 6GB of memory
pri/sec hub - 2GB, 1 CPU.
All of these are running linux (centos or ubuntu). Does anyone have any tips & tricks or best practices to improve the UMP resonsiveness? or, can anyone offer advice on how to figure out where the slowdown is occuring?
