Those outliers were always there of course and could be seen with a little wasted time staring at latency-test and latencyplot, but the histogram approach demonstrates the value of pictures. I was the "mine is better than yours" poster so I have to quibble with the "but these plots...." That was exactly my point to Gene. Focus on understanding and on improving the performance, not on the absolute numbers. > Thanks guys for providing this functionality. Yup. They get my tip of the hat. Regards, Kent PS - thanks everyone for not mentioning the mistake in my offhanded remark to Gene about reducing the sizes of the captured-sample files by reducing the precision of the sample. I was like Wile E Coyote (a Warner Brothers cartoon character for those who don't know). I got up a head of steam and ran off a cliff but didn't know it until I looked down. Sorry. Fortunately, Dewey, et al. have made it a moot point. ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
