Afternoon all,
We have a couple of fairly beefy servers running a 3rd party product. The servers are quad Hex core with 120GB of ram running a system which concurrantly runs a series of "engines" on the box, one engine per CPU core.
Since installation, the performance of the system has been woeful although CPU utilisation and Ram usage are relatively low. On further investigation it appears the disk queues are stacking up against the local disk (rather than the iSCSI attached storage). It turns out the system is reading/writing constantly to the page file although there is well over 50GB of RAM available. The vendor have assured us the system is not limiting its own RAM usage or requesting virtual pages specifically, they are claiming the server is using the memory and not reporting it. I find this rather suspicious and wondered if anyone here had thoughts/things we could check to backup/challenge their claim.
Cheers,
PJ
