Enable Transparent Huge Pages selectively via madvise()

Open kaomakino opened this issue 6 years ago • 0 comments

We, at Snowflake, currently enables Transparent Huge Pages (THP) blindly in the system level to boost the FDB performance. https://forums.foundationdb.org/t/transparent-huge-pages-performance-impact/1398 However, this has a system-wide impact, and not always desired. FDB should enable THP selectively on the memory segments that has the most performance impact.
