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 AMD athlon. Once that happens everything else slows down and performance degrades rapidly. look at the performance numbers in my article. Maybe Remmy can post his old SSL numbers from the benchmarks we ran on tomcat 4. If your shopping cart is efficient, 100 webapps won't matter. Ultimately, the concurrent requests across all webapps will be your bottleneck. After the SSL, the database will be the next major bottleneck. If you're using database sessions to keep track of the shopping cart, use JMeter to figure out the maximum concurrent queries for firebird first. hope that helps. peter lin

For example e-commrece solution, without many bells and whistles - jsut shopbuilder and sopiing cart Each webapp is based on trubine/velocity/torque. Each webapp using it's own firebird database. Can I expect smooth performance on dual xeon with raid controler and lot of RAM (16G) on RedHat EAS?
