. Jens has fixed the request queue aliasing problem and we are no longer
able to break the IO scheduler. This was preventing the OSDL team from
running dbt2 against recent kernels, so hopefully that is all fixed up now.
. The anticipatory scheduler is performing well. I've included that now.
. Also included the CFQ I/O scheduler. The kernel defaults to using the
deadline/anticipatory scheduler. Select CFQ by adding "elevator=cfq" to
the kernel command line. Do "dmesg|grep elevator" to see which one you
are using.
. There is an updated version of the reiserfs_file_write patch here. This
patch addresses CPU efficiency when performing appending writes (ie: the
usual sort).
To do this, it requires that userspace pass "large" amounts of data into
the write() system call. So the filesystem returns a value of 128k in the
stat.st_blksize field from the stat(2) system call. In the hope that some
applications are using that kernel-provided hint.
Turns out that some parts of KDE (kmail, at least) were indeed using this
hint, and it triggers a nasty bug in (at least) kmail: it is reading the
same 128k of the file again and again and again. It runs like a dog.
Ed Tomlinson upgraded his KDE/kmail version and this problem went away.
So that is something for reiserfs users to keep an eye on.
