avgTimePerRequest is the important one for your users. They don't care if you're processing a million QPS, they care how long *their* query took. But you also have to pay attention to longest response times Best Erick On Thu, Nov 18, 2010 at 12:54 PM, Shanmugavel SRD wrote: > > Erick, > Th

average time per request is the total time spent servicing X requests divided by X (in milliseconds I believe). If no searches are being processed, this number doesn't change. It's a measure of how long it takes, on average, to service a single request. avrRequests per second is the total time sin
