You can configure syslog to discard the logging by excluding it from 
all the log definitions. But in any case, if you make logging async, 
then it will cease to be a significant bottleneck on the DHCP server 
(if it ever was).

With async logging, the logs are buffered and written to disk in 
larger blocks - instead of being written for every line of logging.
