Hi Dieter,

I did think that might be a problem, but my DB_CONFIG
contains:

set_flags DB_TXN_NOSYNC
set_cachesize 0 209715200 0
set_lg_max 131072000
set_lg_bsize 26214400

which I thought was fairly generous for what I'm trying
to do, though I admit I don't have any feel yet for
optimising these values.  The whole DIT only has ~15000 
entries with no large objects stored - this is just
an information service for unix clients.

If this were a cache problem, then on a quiescent test
system with no other clients I would expect a subsequent
su to the same user to return a lot quicker, but it gives
the same slow result.

db_stat -c shows no apparent lock problems.  db_stat -m shows
100% requested pages found in the cache, and nothing forced
out of the cache.

Anyone else using Solaris in a similar way out there getting
better results? If so could I get a look at your server's
slapd.conf and client's ldap_client_file?
