test-tlb | Stupid memory latency and TLB tester

test-tlb is a C library. test-tlb has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

quick memory latency and tlb test program. note! this is a quick hack, and the code itself has some hardcoded constants in it that you should look at and possibly change to match your machine. .. and then later down.. if you don't change the freq define (it's in gigahertz) the tests still work, and the absolute time values in nanoseconds are correct, but the cpu cycle estimation will obviously be completely off. in addition to the tweakables in the code itself, there are other hardcoded values in the makefile, where the "make run" script will be testing memory sizes ranging from 4kb to 256mb, and it uses a hardcoded stride of 64 bytes. to give meaningful numbers, the stride should generally be at least the size of your cacheline, although particularly in cases with multiple different cacheline sizes, you might just use different strides and see how it affects the scores. note that the "stride" is still used when doing the random list case, but since the end result will be chasing a random chain it won't be a "stride" in memory as much as just the granularity of the chain entries. you can use odd stride values to
