Two hits can be avoided:  Syslog's line buffering to the log file,
and the communication with the syslog process.

Thanks, I didn't know about asynchronous logging.  Will try when I have
time to set up a test machine where I can risk running slapd+syslog into
the ground.

BTW, anyone got a test program which bombards slapd with configurable
search requests and has some fantasy about varying search parameters and
how many outstanding requests and connections to have at the same time?
