I was afraid of that. Try adding

(or some large number) to the hdb configuration in slapd.conf and then
try the search twice. The 2nd one should be reasonable.


That doesn't fix the problem.

Further follow-up:

Upping idlcachesize to 100000 definitely helped. Searching on a subtree is still about 1/4 second slower with HDB in 2.2 than BDB in 2.1, for those that are interested. Essentially, those looking at HDB will need to set idlcachesize based on the size/extent of their DB.
