OK. > RAM is 2 GB on Linux on Windows is 1.5 GB > No extra applications are running when the same was executed > How much of that RAM is given to Tomcat in each case? > Machine details > > Windows 2000 > 4 CPU 2.66GHz > Service Pack 4 > OK. I can't compare that to the Linux box, as you don't give the same details. > Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64) > Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing) > A couple of differences compared to the Linux box: - A much older JVM, I think - this looks like the original 1.5 release, compared to 1.5.0_18 on Linux. - The client VM rather than the server VM is running. I would expect both of these to slow down the Windows box.

For example, if your webapp accesses an external database, the version of the database software will make a massive difference.

As with all businesses, yours needs to trade off the expected cost of upgrade (including the disruption) with the expected cost of supporting the old versions. I'm not arguing with you - I still see the odd NT 4.0 box, and several Windows 98s ;-). - Peter
