Hi
Despite the fact that this is not a well formulated question. I wonder what tests could be a good subset to measure the performance of the kernel . I have some approaches like phoronix does here :

I am sure postmark/ John the ripper/ Apache are good candidates but I want to ask the community if there is some specific test that you recommend
It depends on what you want to test, specifically. The "kernel" isn't a very specific thing, what most of those tests test is the speed of the hardware, not specifically the kernel itself.
good luck,

Thanks for the feedback . You are right they test the speed of the HW however I have seen that when there is a change in the kernel for network the performance of apache is changed, which make total sense . I think that LTSI should have kind of a test suite with significant test that could help the developer to detect those perf changes. Is very common that one as OS developer make a change in one package ( important one as the kernel ) and do not check how this affect the performance of the OS ( I know is too general , but we might show BKM's) I think this might be a good topic to discuss with the community and we could came with a solid recommended test suite in the LTSI project. Feedback more than welcome Regards Victor Rodriguez
