Re: increased performance

[David Wright <ichbin@shadlen.org>]

You have a ~100 entry database and you have performance problems?! I 
think there must be something very basic you have forgotten to do. 
Here's a checklist:

1) index eq,pres on all common search keys -- this should reduce slapd 
CPU consumption;
2) set cachesize larger than your total number of attributes, and 
dbcachesize larger than the total size of /var/lib/ldap in bytes (on a 
large system, this might require buying more RAM) -- this should reduce 
disk accesses;
3) loglevel 0 (or, if you must, loglevel 256  and use - in syslogd.conf) 
-- so logging won't slow you down;
4) run nscd on your clients -- greatly reduces frequency of lookups;
5) tune your ide disk with hdparam, or use scsi disks

Once you have done all these things, I would be very suprised if you 
still have problems. But if you do, I doubt moving to a ramdisk will 
help. Writes to disk under Linux are asynchronous by default, and reads 
will most often be from slapd's in-memory cache.
