  Why ? Do you need 4 CPU to soak your hard drive ? There is usually one
partition for every logs on the machine, so you don't get a lot writing
many log files at a time. And if you're that concerned with performance,
then it's not multi-foo that you need, but aio's, and a big nice epoll
loop to dispatch /dev/log clients. And absolutely no multiple processes
that you will else have to deal with locking, especially locking of
output files, which would be a huge mistake.

  The syslog daemon shall not eat anymore than 0.01% of your CPU. Why
would you need to bloat it for god's sake ? It reminds me of so called
network monitors that are so huge, that they mostly measure their own
fat. A multi-foo syslog daemon is just plain silly.
