Running 2.2.15 here for about a week, and it is definitely slower than
2.2.14 and older kernels when accessing the same disk.
In my own case, doing a CVS import (reading from local drive) and
Netscape Mail (on an NFS-mounted home dir) causes a very noticeable
slowdown.
In 2.2.14, I could perform an import while reading mail with only the
occasional delay. Now, a CVS import causes massive delays in screen
updates in Netscape Mail, often one-three seconds per message-view.
The CVS process is always busy in disk wait during the import (this is
normal), so it looks like other processes are being starved of I/O,
regardless of which partition is being accessed. Also regardless of
read/write patterns, as the CVS process is reading from a local drive,
and Netscape Mail is a combination of reading and writing (both are
slow) to an NFS drive.
"renice +19 <cvs import process>" helps the situation a little, but not
very much.
What diagnostic information may I provide, which will give clues to help
diagnose this problem? .config for 2.2.15 is attached. Hardware is
Dual P-II w/ a single 10G IDE UDMA drive, and rtl8139 network hardware.
