BTW: Fedora switched back to 4k pages a while back. The 64k page thing is one of those areas where ARM should have an advantage over x86, but so much software fails to work with 64k pages that its not yet worth it. So, give fedora a try on aarch64 again, with F29, its almost at 100% package parity with x86 once you remove packages specific to x86. ARM/linaro/etc have been hard at work for the past few years getting the long tail of compilers/libraries working enough that all the higher level stuff has a change to generally work. The perf thing is a problem because there are a lot of microarch specific counters, but frequently they don't get published by any particular cpu vendor. So, your left in the dark about them. The best solution at the moment is call your vendor and demand a more complete list.
