It has not.</P> <P>I've spent a couple days rummaging through configuration files and increasing CherryPy thread settings and the allocated ram for DBX, but the interface is still very slow.</P> <P>Is there an optimization guide I'm missing or an obvious fix I'm missing?</P> Tue, 24 Jun 2014 13:21:49 GMT https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117510#M1393 mcrawford44 2014-06-24T13:21:49Z https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117511#M1394 <P>Is it maybe your browser that's slow? You seem certain to rummage around the server, but I'd check that first.</P> Tue, 24 Jun 2014 13:41:04 GMT https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117511#M1394 martin_mueller 2014-06-24T13:41:04Z https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117512#M1395 <P>I don't believe so.

If that's slow then it's something on the server, if that's fast then it's something in the network.</P> Tue, 24 Jun 2014 15:08:26 GMT https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117513#M1396 martin_mueller 2014-06-24T15:08:26Z https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117514#M1397 <P>At a high level, reporting and UI slowness is more often caused by less-than-ideal disk IO, rather than CPU and ram and this goes double for VM's. Splunk reads a lot from disk and has to do it fast for reports to be fast. VM's suffer just because all else being equal they usually have less IO throughput than a physical host.

Our VM OS drive is extremely low powered for some reason.</P> Tue, 24 Jun 2014 16:55:21 GMT https://community.splunk.com/t5/Monitoring-Splunk/Splunk-Web-performance-slow-for-VM/m-p/117515#M1398 mcrawford44 2014-06-24T16:55:21Z
