Hello, Would you be able to share your thoughts/experiences on performance monitoring using hardware counters in Linux?
I am currently using *perf* tools that come built in with the kernel to measure the number of cycles a specific program takes. Now, I can't seem to figure out how to measure the number of cycles per function call. For example, I would like to measure the number of cycles it takes for SHA1_Update() from libcrypto when using the sha1 ASM instructions compared to not using the sha1 ASM. Thanks, Amit
