| | | | | tl;dr "Transparent Hugepages" is a Linux kernel feature intended to improve performance by making more efficient use of your processor's memory-mapping hardware. It is enabled ("enabled=always") by default in most Linux distributions. Transparent Hugepages gives some applications a small performance improvement (~ 10% at best, 0-3% more typically), but can cause significant performance problems, or even apparent memory leaks at worst. To avoid these problems, you should set enabled=madvise on your server... | |

| | | | | If you build an application that uses large, contiguous amounts of memory, it can increase your performance if you allocate this memory in so-called huge pages. Linux offers you two ways of doing that - a legacy way and a modern way. This article describes the modern way of using huge pages, so called transparent huge pages (THP) and applies the techniques from a previous article to verify that we actually got huge pages. The article starts by giving a super-short recap on how paging works and why huge p... | |
