Possibly the sync operations triggered by syslogd make it
*really* slow. You might want to look up the documentation
of your syslog daemon how to turn off syncs for the file
Samba is logging to.

If your compliance requirements are such that you have to
log everything, then there is probably not much you can do
here. Logging everything is *very* verbose though, sure. You
need to decide and configure what to really log to comply.
