Where as in a system who is spending time writing/reading from/to the swap area performance will degrade considerably. // Michael Medin On 2009-07-09 09:37, Tore Lønøy wrote: <blockquote cite="mid:c9c496260907090037y7cd6698doc55a59f33c4ad18f@mail.gmail.com" type="cite"> This is true for some cases but we have a few servers which are using 75% swap (8GB RAM, 8GB Swap), which are blazing fast even then.

I have for some time now tried to find a way to monitor performance bottlenecks related to shortage of memory on Windows, with no luck. As far my knowlegde of memory bottlenecks concern, using NSClient++ command CheckMem and argument physical, is far from enough. Also, monitoring windows performance counters, like Memory \ Pages Out/sec is no good either since it doesn't support average results. There is alot of documentation on how to determine that memory is a bottleneck, like e.g.: <a moz-do-not-send="true" href="http://support.microsoft.com/kb/555223" target="_blank">http://support.microsoft.com/kb/555223</a> But, for what I understand, using nagios to determine this is hard. So how do you guys locate memory bottlenecks on windows machines, with or without the help of nagios? </blockquote> </div> </div> By checking the swap usage. Basically, when a system starts swapping performance will go downhill very, very fast. The disk is several hundred orders of magnitude slower than the RAM. If you have high swap usage, you should buy more RAM for your servers (or modify whatever programs are running on them). -- Andreas Ericsson <a moz-do-not-send="true" href="mailto:andreas.ericsson@op5.se" target="_blank">andreas.ericsson@op5.se</a> OP5 AB <a moz-do-not-send="true" href="http://www.op5.se" target="_blank">www.op5.se</a> Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. </blockquote> </div> </div> <pre wrap=""> <hr size="4" width="90%"> ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
