Keith Wall commented on QPID-7038:
----------------------------------
The patch looks like a useful improvement to me. On my machine it saves about
20%-30% off the number of iterations to achieve the same answer. I did notice
towards the end the run the algorithm tends test a number of fractional target
rates. Perhaps these should be pruned by have the target rounded to an integer.

> Key: QPID-7038
> URL: https://issues.apache.org/jira/browse/QPID-7038
> Project: Qpid
> Issue Type: Improvement
> Components: Java Performance Tests
> Reporter: Lorenz Quack
> Attachments:

>
>
> Currently, running the performance tests takes a considerable amount of time.
> There are some ideas floating around about how we could cut down on the
> execution time. Each of these (and any additional) ideas should be evaluated
> for their impact and implemented accordingly.
> In no particular order; enumeration provided solely for easier reference:
> # because we retry a failed target rate is expensive we might want to change
> the hillclimber to be biased and not divide the range 50:50 but perhaps 25:75
> to decrease the times we miss a target
> # we might want to increase the {{hillClimberMinimumDelta}}
> # we could experiment with using the achieved rate as a guide for the target
> rate for the next iteration
