Remy,

With just 1 user, it appears 3x as slow. I understand the max throughput will be better, but did not expect this performance degredation with just 1 user, I'd assumed slight degredation overall and a lower max users.

Don't suppose you could answer my questions 2 & 3 ?

Thanks,
Pete.

I've just got my app load balanced between Apache 1.3 & 2xTomcat 4.1.29, JK, SunJDK1.4.2, all seperate boxes. I have set heap site (JVM settings) same as my Tomcat 5.0.18, and guessed minProcessors=100 and maxProcessors=300 for server.xml's - config different to 5.0.18.

It's appears about 3x as slow as a single 5.0.18.

I have three questions re this:

1) Has any1 experienced this and found a solution?
2) If I can't get T4.1.29 up2speed, and want to loadbalance with T5.0.18 / Apache 2, do people actually use this in production without any major issues?
3) If I go point 2, then the only way I've found to provide apache
loadbalancer redundancy for those versions is LinuxVirtualServer. Is that correct?


Any comments would be appreciated.


If you're comparing with 5.0.18 with the HTTP connector, I'd like to point out that the HTTP connector has a higher max throughtput than using AJP with a native webserver (esp if TC and the native webserver are running on the same server).
If you want to compare the two releases, you should probably be using the same configurations ;)
