Re: [OT] computer performance with jsp/servlets/struts
Is there any kind of benchmark results table or technical comparation between tomcat, jetty, iplanet, resin...? I've been searching google without success... I need something because much faster or much slower is not enought for me. Thank you! Manfred Wolff wrote: Dan Allen wrote: I only ask this to see if I can make my life easier.

RE: [OT] computer performance with jsp/servlets/struts
There were some issues with session serialization which were resolved in the latest nightly builds. You could try disabling session persistence although it would be better to resolve the serialization problems. If I understand correctly, in a low memory production environment those serialization mechanisms have to work. The other issue is that the tomcat manager reload application is 10 times faster (10-20 seconds vs 1-3 seconds on my machine 1.8g, 512mb, w2k) than a stop and start of tomcat. Actually, the first few times I used the reload function it was so fast, I didn't believe it actually worked.

Re: [OT] computer performance with jsp/servlets/struts
It seems from your email that you are experiencing a lot of swapping , an indication that you are running low on memory. Of course more Mhz doesn't hurt :) . I'm currently using a PIV in the office with about 392 MB of memory and tomcat application reloads and jsp reloads are no where near the time you state. Just under a few seconds for a jsp page which has changed. I don't see much swapping unless I use other stuff like netbeans, sapdb and the like. Even then the recompile is pretty fast. Hope it helps.

Yeah, plus I am hitting the page from localhost with mozilla, which isn't exactly generous with resources. Obviously I man can't develop if his computer eats up the RAM like mine does.

RE: [OT] computer performance with jsp/servlets/struts
I'm using a 2GHz with 512MB RAM (Win2K) and I can undeploy/clean/compile/deploy (using Ant) my entire project in just under 30 seconds. The project has about 250 .java files and generates a bunch more using XDoclet. A pretty resource intensive build. The biggest difference I'd say is the CPU. I have a 1.5 GHz at home with 1GB of RAM and this one is *much* faster. Then again, I have a 1.5 GHz, 768MB RAM Red Hat machine that can do all of the above in about 1/4 the time. Linux is *a lot* faster than Windows for compiling/running Java.

RE: [OT] computer performance with jsp/servlets/struts
I would suggest you try to tune Tomcat memory by using -mx as a JVM parameter, I may help reduce the swapping. -Original Message- From: Dan Allen [mailto:[EMAIL PROTECTED] Sent: 11 March, 2003 06:09 To: Struts-User List Subject: [OT] computer performance with jsp/servlets/struts I only ask this to see if I can make my life easier.
