What are the main reasons of a poor EPO performance and what can I do about it?
– Possible Reason 1: not eneough memory in the epo server for preventing memory swapping: —> check in Task Manager of EPO Server if Physical memory is greater then Peak Usage of Commit Charge and checkout the requirements described in the EPO handbook. – PR 2: slow disks: —> Use preferably SCSI- or SAS-disks, RAID 5 and high diskcache – PR 3: large windows eventlogs (can make EPO very slow. Sometimes windows servers log more than 100 messages every second!): —> Look for epo data files on your EPO server that are larger than 1 Mb. Adapt the epo event log probe on that devices for filtering irrelevant messages (often Windows security logs messages like succes or failure audits).. – PR 4: huge number of measurements because of not default probe scheduling (example: read every second 500 bandwidths from 10 routers) —> use the probe filter to prevent measurements within same bandwidth (almost the same measurement) being stored into the database (probes can measure every minute witho
