Hi, we have such a problem with our server performance. Let me first introduce our server;we have a HP Proliant ML370 host machine with double CPU, each of which is Xeon 3.0 GHz. with 1 MB. L3 cache. But unfortunately, we cannot get the performance of parallel processing to the degree we want. Each Xeon CPU is seen as 2 CPUs, because of being Xeon and HT technology, and totally 4 CPUs are seen while the server is running by the OS. But the point is that those 4 CPUs are running sequentially, not parallely. As a result, while running an application esp. needing CPU, on the server, we cannot use the total CPU power upto 100% or close. In other words, there is little or zero performance gradation while running the application on our server when compared to a normal PC. We use RHL 9.0 and the kernel is 2.4.20-20.9. I think that the kernel does not let to use system resources totally. Perhaps another RHL 9.0 kernel might not only let to use system resources fully but also runs our applicatiom without a problem. I remember that with RHL 7.3 version, there was not such a problem. All CPUs were working parallely with it, 7.3 and we get the full CPU power. But now our CPU utilization is about 25-30%. We have to use RHL 9.0 from now on, and would be better to run the CPUs parallelly. My question is that have you ever encountered such a problem, and do you have any idea to overcome such a situation? Do you have any supposal, if any, i like to hear.
