Yes, so do I, but I think it can´t be a rule, but I try to understand the why´s, for example, if you have a Dual-P4 it would be worth to have 6 simultaneous requests seted, but we know that Coldfusion has to many ways to optimize the code. So, "perhaps" with one application with a code well optimized you could set it to 8 When I had a Dual-P4 I get the better configuration with 10 simultaneous request. Now, we upgrade the server to a Dual Processor Dual Core, and it means that we have almost 4 processors embeded, besides the Dual Core technology is based in the Xeon servers, that give a performance much better than a Dual-P4 So, I "thought" the number of simultanous requests could grows, too. In the other side, the old server (Dual-P4) showed some overload signs in the system (load, CPU) when it was handling 10 simultaneous request, but it isn´t happening with the Dual Processor Dual Core server, it don´t shows overload signs in the system, that seems this number could be improved. But it´s only thoughts... Thanks, Ronan > 30 seems high to me, but maybe I am off base...? Do you have processes > that are long running taking up those job slots, or are they all quick > templates?
