syslogd revisited

Again on syslogd.

I am not reporting the problem so often reported in the past
(syslogd and klogd eating all CPU, "select: Bad file descriptor",
"last message repeated 79172 times" , etc). I am not suffering of
this problem with my current setup (RH 5.2, 2.0.36, sysklogd-1.3-26).

However, I am rather unhappy with the amount of CPU which
syslogd seems to use under normal circumstances.
For instance, right now I observe a syslogd using about 60-70%
of a 533MHz LX to write about 13kB per minute on a file.
This is ridiculous. Heck, in this case the messages are generated
by sendmail, which does that while cruising along at 0.1% CPU.

syslogd therefore appears as the principal bottleneck in
our systems' performance. Is anybody else observing that?
