Pardon my ignorance but how do you share one port between multiple instances of tomcat? Are you talking launching tomcat 100 times (100 JVMs), or are you talking 100 Hosts configured in server.xml? Adam On 03/30/2004 05:28 PM Reynir Þór Hübner wrote: I just wanted to post my info on the subject

Hi, I just wanted to post my info on the subject, even though I dont have 100 hosts on a single machine. We run near 60 hosts on one machine, in 10 instances of tomcat. memory usage has been the biggest problem as our application use cache:ing alot to increase performance. all of those hosts a

the only way you will know is to stress test it. I would recommend doing a small test with 10 webapps and a fair amount of load. I can tell you right now if you're not using SSL/TSL hardware acceleration, that's going to be your bottleneck. 20-25 concurrent https requests will max out a 2ghz

God save our apps from any memory leaks. Of course we will test them for this issue. And perform stress testing 20 sounds fair enought. Frankly I don't expect too much traffic per e-shop. Niki Shapira, Yoav wrote: Hi, We have tomcat instances that run ~20 webapps without a problem. Beyond that, w

Hi, We have tomcat instances that run ~20 webapps without a problem. Beyond that, we haven't tried, but then again that's why we have tools like JMeter, no? ;) In large part this will depend on the soundness of the application. Especially if it's 100 of the same app, because then each memory lea
