Just curious... My biggest latency problems (as observed by me, the user) happen when a program needs memory, or launching a new program, and the kernel begins forces dirty memory to disk. This results in an unholy seek storm of mixed writes (flushing, maybe a little swap) and reads (new program loading). Streaming audio/video almost always starts freezing up during this as well. I don't suppose LatencyTop would help track anything down in that case, would it? -- Zan Lynx <[EMAIL PROTECTED]>
