RE: hardware recommendation, Tomcat with Apache web server
Why Win2K Server? If you want to stick with Windows, save some money and go with just Win2K Professional. Unless this machine is doing something else in addition to Apache and Tomcat I don't know of any advantage in going with the Server edition. Why RAID-0? Disk performance really shouldn't be that much of an issue once classes have been loaded by Tomcat. RAID-0 increases the chances of a failure. RAID-5, RAID-10, RAID-1, or no RAID at all would be safer choices. As to CPU choice/quantity, that really depends on the load that you expect. How many concurrent requests do you think you will see? It also depends quite a bit on the application itself. Have you benchmarked your application on anything? I would create a test routine and hit the development machine to see how much of a load it can handle -- then you can use that to get an idea of how much hardware you need. -Original Message- From: Paul [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 1:35 PM To: Tomcat Users List Subject: hardware recommendation, Tomcat with Apache web server what would be appropriate hardware for a Tomcat with Apache web server running on Win2k server (for a public OLTP-type web service with database backend running on its own dedicated machine)? probably use striped (raid-0) scsi drive system, but not sure if dual cpu's required, P3, P4 or Zeon system would be appropriate? -paul lomack - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: hardware recommendation, Tomcat with Apache web server
thanks all, the comments given here have been great toward selecting hardware for Tomcat/Apache web server in the following ways: * super fast and heavy hard disk access not so important if no database on same machine * 64-bit cpu (such as opteron) could be quite significant choice (where hard disk access is not primary) * load testing on development machine useful measurement in choosing hardware for production system -pl - Original Message - From: Paul Sundling [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 5:38 PM Subject: Re: hardware recommendation, Tomcat with Apache web server I forgot to point out that in the test where opteron was beating xeon 2 to 1, it was a 2.8 Ghz Xeon losing to a 1.6 Ghz Opteron!!!

At 400 users, Opteron was 35 seconds, and Xeon was near 80 seconds. And at 500 users Opteron was about 50 seconds, and Xeon was near 100 seconds.

Re: hardware recommendation, Tomcat with Apache web server
Any decent dual-proc server with 1-2GB RAM would be more than sufficient, assuming your application is sane. My production servers are dual-proc with 6GB RAM (RH Linux) and they easily handle hundreds of simultaneous users (not to mention a couple dozen Tomcat instances) with intensive CPU usage and intensive filesystem I/O (RAID 5).

RE: hardware recommendation, Tomcat with Apache web server
Assuming your application is well written and not doing anything insanely complex, any modestly configured box not running a DB would handle that load fine. Start with a ~2ghz server, w/1gb of ram as your baseline, and then add in the level of redundancy you want - failover nics, failover cpus, RAID configs, etc... -Original Message- From: Paul [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 5:01 PM To: Tomcat Users List Subject: Re: hardware recommendation, Tomcat with Apache web server not sure what the load is going to be ... would be nice to be able to adequately handle aprox. 20-30 simultaneous users.
