Hi, I have began to work on some set of performance tests. I think it would be useful to have some standard set, because as far as I know, there is just little of performance testing and every of the few tests someone does is unique. I want to propose my ideas before I start to really write it, to fix possible complications. Mixing performance with regressions tests wouldn't be a good idea, so I thought about creating another category on the main level of tests (something like xfstests/tests/performance). Or it would be better to put it into entirely new directory, like xfstests/performance? >From the beginning there would be some basic test cases, like sync/async read and write. Hopefully more natural cases, like a database server would be added later. For the IO testing, I want to use FIO for the specific workflow and eventually iozone for the basic synthetic tests. What I'm not sure is how a comparison between different versions could be done, because I don't see any infrastructure within fstests for cross-version comparison. (What would it do with regression tests anyway...) So I wonder if it should be done in this set at all. So the set would only print the measured values. Some other tool (which can be also included, but is not directly part of the performance tests set) could then be used to compare and/or plot graphs. Comments and questions? :-) Jan Tulak -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
