Speeding Up The Linux Kernel With Transparent Hugepage

[Sabre]

Phoronix article

Transparent Hugepages will not speed-up all Linux applications, but with memory and/or CPU intensive applications, it will cause some performance boosts, even without any user-land modifications. From the handful of Phoronix Test Suite benchmarks run, the best example we found was with NASA's OpenMP-based Fortran-written NAS Parallel Benchmarks. In particular, with the IS.C test, the performance jumped by more than 20%.

Good read if you are into that sort of thing

interesting reasons both pro and con.

bigger blocks are making hdd's better and fasterer, especially with larger data sets.

i could see how this would make sense for "hungrier" applications.
