I'm not. But If components (CPU, disk IO, ...) are overloaded the value of response time increases and not stabilize. For example: req/s = 500 ----> 1.23 seconds req/s = 1000 ----> 2.44 seconds req/s = 1500 ----> 5.78 seconds req/s = 2000 ----> 10.5 seconds req/s = 3000 ----> 17.5 seconds req/s = 4000 ----> 39 seconds Here, it's happen this: req/s = 500 ----> 1.23 seconds req/s = 1000 ----> 2.44 seconds req/s = 1500 ----> 5.78 seconds req/s = 2000 ----> 4.77 seconds req/s = 3000 ----> 6.15 seconds req/s = 4000 ----> 5.5 seconds Very stranger !! What's happen ?? Ricardo But I dont thought that components (CPU, disk IO) can be . Because my machines have good perfomance (Core 2 Quad, 4GB RAM, network 1GB/s).
