Yeah that would be my concern, if I am scaling my app by clustering the last thing I would think I would want to do is slow it down with constant DB calls. Like I said though I have never tried this. Our environment is uses sticky sessions and we are happy with the performance/uptime. > Again, though, clustering multiple instances on a single physical server >isn't something you do to improve performance, but rather reliability. 90% agree. I still imagine you can get a bit more out of your memory so if that is a bottle neck in the app you may see some performance. Maybe I am flat out wrong though I can't speak from experience on this one. Our environment is pretty different than this type of stuff we have 2 massive powerhouse servers (IBM p570 w/16 CPUs) virtualized in AIX . We run 64 logical partitions each one running anywhere from 2 - 10 ColdFusion instances, the higher instance counts are for staging. We do CPU time sharing so each logical partition gets approx 2/10 of a CPU + 2-4 gigs of ram and most logical partitions can borrow upto a full CPU worth of processing if it is available.
