Public bug reported:
Hello,
my CPU usage rises when there are ~16.2GB of log files (each ~40kB),
that are not compressed. Log files are in 15 separate directories and
the new ones are continually added. With such volume, it makes ~10% of
CPU (Core i7-2600K) wasted. CPU usage increases rapidly with a small
growth (it seems to be exponential).
Logs are located on 360GB ext4 partition (26% used), mirrored on 2 HDDs
(md).
I do have a workaround - I can tar and delete that files and the speed
comes back. Anyway, I think this is a bug, so I report it.
Ubuntu 10.10, I expected low CPU usage, but got high CPU usage.
