Excerpt from the Postfix 2.0.8 README_FILES/LINUX_README file in case 
it proves interesting:
-----------------
LINUX syslogd uses synchronous writes by default. Because of this,
syslogd can actually use more system resources than Postfix.  To
avoid such madness, disable synchronous mail logfile writes by
editing /etc/syslog.conf and by prepending a - to the logfile name:

    mail.*                          -/var/log/mail.log

Send a "kill -HUP" to the syslogd to make the change effective.

Cheers,
