Hard to say, I wasn't recording them in the benchmark data I keep - but in just looking at it, I would say yes. >>>Also what about min/max std.dev? >> >> Those varied a lot from one run to the next anyway - just because I've >> always been dealing with very short durations - but I did notice that >> the 'max' seemed to consistently read higher than my prior benchmarks >> - but only by 1-2 seconds (1000-2000ms).

If it were something in the HTTP Request HTTP Client sampler, it might make a difference if I switched to a different sampler. If it is a problem that is global to all JMeter samplers, then it won't help at all.

Not that I can see. Everything appears normal to me. -- Robin D. Wilson Sr. Director of Web Development KingsIsle Entertainment, Inc.
