We have 601 licenses of 10.1.1 on Red Hat Enterprise Linux AS release 3 (Taroon Update 1) Kernel 2.4.21-9.ELsmp on an i686 (Dell 2600 with 2 multi-threading processors and 6G memory.). Memory is crucial for best performance. The most users at any one time has been 290. Performance smokes (highly technical term). We moved from an HPUX 10.0 and got 3x the disk io and 10x the cpu crunches. Our day end runs 3x faster (disk io bound). We've been running since conversion with no down time for 4 weeks. Another benefit is considerable less cost, maintenance, and support expense. uptime load averages are higher but we believe that is because of the multi-threading pushing the io faster than the io can happen and processes get stacked up in memory. It causes no ill effects and just something to get use to. We've had it as high as 40+ and it clears up in a short time with no noticeable performance hit to the users. The HP would have died long before getting that high. We love out Linux (if loving an inanimate object is possible).
