We can run 75 to 125 instances of tomcat on a single Linux server with 12 cores and 128GB RAM. It works great. CPU is around 25%, our JVMs are not throwing OOMEs, iowait is minimal, and network traffic is about 30Mbps. We're happy with the results.
Now we're upping the ante. We have a 48-core server with 1TB RAM, and we're planning to run 600+ tomcat instances on it simultaneously. What caveats or pitfalls should we watch out for? Are there any hard limits that would prevent this from working as expected? -Eric Disclaimer : This email and any files transmitted with it are confidential and intended solely for intended recipients.
