for my team’s enterprise product, we have been using jemalloc 3.6. Currently, we are trying to upgrade to 5.3 version. In the 5.3 version, we are noticing that there is a slightly better performance when running with a 64k page size than with a 4k page size. This is on linux 4.4 kernel. My question is, is there any harm in setting page size to 64k in linux (ie, setting -with-lg-page=16 at compile time).
