Re: JBossCache Developments

by Manik Surtani

Hi Mikko. Good to hear from you! I've cc'd the jbosscache-dev list as well, in case others are interested in following.

Yes, this is something I started a while back, the goal being that most benchmarks are pretty useless and are "tweaked" to look good by using a specific usage pattern, configuration and hardware. To make benchmark comparisons more realistic, I allow people to write their own "test", a simple use case to reflect real-live cache usage (transactions, #puts vs #gets, type and size of payload, etc) and to plug in different cache configurations or even engines (JBC 1.4 vs JBC 2.0 vs EHCache, for example) It still has a way to go though. > > I have too different "clusters" to use.

Internally, a TestResult object represents the measurements, and reports are created using the ReportGenerator interface. So far I have a CSVReportGenerator but others like a GraphicalReportGenerator which uses gnuplot should be simple to implement. (I just used the CSV reports and plugged them into Excel and drew graphs there!) One of the other things I'd like to add to the test result is throughput. Calculations are made on various statistical analyses on time taken for puts and gets (mean, median, mode, max, min, standard deviation) but calculating throughput (repplication speed in bytes/ sec) as well as requests per second would be useful metrics to capture. > Second, I have checked out the latest development branch to start > thinking the architecture for the striping cache we discussed about. > To sketch out a good plan I still need to know the code better. Sure, this would be a separate thread anyway.
