Thanks for your reply. The hardware is Xeon 5160, two processors. The chipset is The IntelĀ® 975X Express Chipset. I want to access the following stats: L2 cache miss (the lowest-level cache), average memory latency, memory access rate/numbers Do you think it is possible to throttle the number of

Hi, I don't think I already replied to this message. To answer your question, I would need to know the type of hardware you are using. On some processors, it is possible to sample cache misses and get the miss latency. 2009/3/3 Ming Chen : > Hello All, > > I am new in perfmon. I am involved in

Hello All, I am new in perfmon. I am involved in a project in which we need monitor the latency of each memory access, the memory access rate, and the number of read requests, write requests, etc. I think perhaps perfmon can monitor all of the information I mentioned. I have read some documents re
