Hi, Unfortunatly I cannot move to a linux platform because this machine is also used for Microsoft .net WCF webservices. Erdas Appollo 2011 runs on the same machine so that should be an equal comparison. Both go through IIS and AJP13 ECW data is on a raid 5 configuration with 'default' 5400 rpm 2.5" disks (6x 500GB disk in a 1U server)
Advantage of Apollo 2011 (with JBoss) is that it seems to use 64bit native ECW dll's. I couldn't manage to get Geoserver working with 64bit jdk, GDAL, 64bit jai and ECW support so that's all 32bit. In this case it should not really matter I guess.. Apollo seems to perform better then Geoserver when more concurrent users are defined than there are tomcat/geoserver instances. Some test with JMeter (6 concurrent users, 300 samples taken) results so far: Geoserver: Random JPG WMS requests of 800x800 pixels (with 6 geoserver instances) take on average 1400msec Apollo 2011: Random JPG WMS requests of 800x800 pixels take on average 1100msec I followed most of the rules described here: http://docs.geoserver.org/latest/en/user/production/index.html Are there any suggested settings for JAI, WCS, WMS (Max rendering memory, etc) and Coverage Access Settings? My current JVM (JDK server) settings: -Xmx1300m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:+UseParallelGC Thanks in advance for any tips/tricks, Sjoerd On Mon, Feb 28, 2011 at 10:59 AM, Andrea Aime <[email protected]> wrote: > On Sun, Feb 27, 2011 at 7:12 PM, Simone Giannecchini > <[email protected]> wrote: >> >> Ciao Sjoerd, >> I would conside to move to linux, you should be able to squeeze even >> better performance due to better OS caching. > > Yep, in the last wms shootout all the tests that were performend on linux, > with the same hardware _and_ > wms server (OS being the one and only difference) were faster by a good > margin (20% and more if memory > serves me right). > GeoServer wise we did not bother to run official test on windows due to that > difference (there was not much time > available so only only worked on the more promising alternatives) > Cheers > Andrea > > -- > ------------------------------------------------------- > Ing.
