One instance, multiple instances, or divide it up into two or more virtualized servers each with one instance?Unless you have concerns about stability of TC6 or your own application, one big JVM with a ton of threads would be my recommendation. Virtualization or multiple TC instances only adds overhead with no other real benefit. (If you run multiple applications, multiple TC instances might make sense).Is Tomcat meant to run as one instance with that much memory, or is it optimized for a different amount of memory?Tomcat shouldn't care. I think that thread synchronization is faster than full context switching, but that can be very sensitive to the platform, OS, and tuning parameters you might have (in the OS). Java is perfectly happy to run with 8GB.I realize with the options I mentioned above there are implications regarding high-availability and performance, but I'm not sure exactly what they'd be. Perhaps someone with more knowledge of this kind of stuff could comment.If you trust your operating system (I would trust any UNIX and UNIX-like OS, and Windows is somewhat dependable if you don't ask it to do too many things), then a single instance of the OS on a lot of hardware is just fine: go for it. If you are concerned about your OS's stability, then by all means run multiple instances of the OS and load balance between. From a strict performance standpoint, less is more, so stick to one OS and one Tomcat instance on that big, fat machine. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGqOyq9CaO5/Lv0PARAlTDAJwKFLgizNh/MatDmEupjdLvLvvDWgCfbHSj XLO50tctVgV5w+N/qwYYZEQ= =DJLh -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
