But in a situation where you have many slow operations (such as a complete syncrepl refresh on a large DB) you need more threads, just as Ando recommended.
I'm still quite skeptical given what I've seen in the past. ;)
I've mentioned before that yanking up 'threads' in slapd.conf did help at our site some years ago. Fewer requests took abnormally long time that way. (Possibly more threads degraded the _average_ response time, but that was fast enough anyway.)
Some server stats, maybe we were half as big/active then: 60-90 new connections and 300-500 requests per second. (Just samples just now and a few other times). Can exceed 6000 concurrent connections. 340000 entries. 5 bdb databases, though we used ldbm back then.
