Vdbench warmup= parameter and run 'avg' numbers
By Henk Vandenbergh-Oracle on Sep 02, 2010
For the "avg2-xxxx" that vdbench puts out at the end of the test run, I was wondering if there was anyway to tune vdbench to use a different starting interval for the average, something other than 2? I've been running tests and we have some cases where it actually takes a while for the IO to reach a stable state. "
There is an elapsed= and an interval= parameter, and Vdbench502 also
has a warmup= parameter.
Normally only the first interval is ignored, but with warmup= the first 'warmup= / interval=' intervals are ignored.
Do realize though that the total elapsed time is increased by the warmup time.
will run for 70 seconds, with only the last 60 seconds included in the avg_11-70 totals.
