-[[!meta title="Disk I/O Performance Tuning"]]
-
-The most obvious reason for the Hurd feeling slow compared to mainstream
-systems like GNU/Linux, is very slow hard disk access.
-
-The reason for this slowness is lack and/or bad implementation of common
-optimization techniques, like scheduling reads and writes to minimize head
-movement; effective block caching; effective reads/writes to partial blocks;
-reading/writing multiple blocks at once; and read-ahead.  The
-[[ext2_filesystem_server|hurd/translator/ext2fs]] might also need some
-optimizations at a higher logical level.
-
-The goal of this project is to analyze the current situation, and implement/fix
-various optimizations, to achieve significantly better disk performance. It
-requires understanding the data flow through the various layers involved in
-disk access on the Hurd ([[filesystem|hurd/virtual_file_system]],
-[[pager|hurd/libpager]], driver), and general experience with
-optimizing complex systems.  That said, the killing feature we are definitely
-missing is the read-ahead, and even a very simple implementation would bring
-very big performance speedups.

-Possible mentors: Samuel Thibault (youpi)
-
-Exercise: Look through all the code involved in disk I/O, and try something
-easy to improve. It's quite likely though that you will find nothing obvious --
-in this case, please contact us about a different exercise task.
