Hi Quanah,

I've transferred one of the nodes to back-hdb and the performance appears to broadly match back-bdb.

Is there a simple test I can perform to confirm that it is indeed using back-hdb?

For completeness here's the result of my timed search:

bash-4.1$ time ldapsearch -H ldaps://rowan.authorise.is.ed.ac.uk:636 -b 'ou=staff,ou=law,ou=hss,dc=authorise,dc=ed,dc=ac,dc=uk' -a always "(&(eduniSchoolCode=S26)(eduniCategory=101)(eduniIDStatus=300))"

# numResponses: 425 # numEntries: 424

real 0m0.902s user 0m0.054s sys 0m0.025s

No, that's enough, thanks. So it is MDB specific then. ;)
