really slow queries

["Andy De Petter" <adepette@krameria.net>]

Hello,

We are evaluating the OpenLDAP software.. We are currently using 2.0.7, with
Sleepycat 3.1.17 on a Solaris 7.

After instaling the sofware, we tried some stresstests on the daemon, and
something very weird happened.. After inserting about 70000 entries in the
LDAP (very simple ones, only sn-cn-uid attributes), we tried to do some
simultaneous queries ....

After starting up a few hundreds of queries at the same time (searching on
indexed "sn" attribute), the load of the machine rises up to >20 ...

We started doing some other tests, and it seems that one simple query
(searchfilter like '(sn=mysn)') takes upto 15 seconds !!!!

Have we overlooked something, or is this normal behaviour?

TIA,

-Andy
