I have general questions regarding a typical Linux system's speed and wonder this is right place to ask these questions. If this is not, Could someone point out which group I can post. With following typical components on a motherboard: 512 MB 10K RPM DRAM, Intel 850 chipset with 64-bits Data bus width and 400MHz Data Rate, 32-bit/64-bit PCI 2.10 bus (33MHz/66MHz) 20 GB Hard Drive Does Intel 850's 400MHz data rate fully used or not on 66MHz bus speed? As speed of these components are measured by rates, I am wondering how one can evaluate the system's speed roughly in terms of using MB/sec so that one can see potential bottleneck or trend of improvement. On Windows, using PCMark2002 benchmark software from MadOnion.com, one can see 20-70 MB/sec on HD, 700 - 1,400 MB/sec on DRAM. Is there a way one can measure system bus actual speed under Linux or benchmark for DRAM, HD? In addition, if I like to add a 1GB Network Interface Card for clustering two same machines, should I add a 32-bit NIC card or 64-bit NIC in terms of performance, and why?
