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 On 08/08/13 16:45, Quanah Gibson-Mount wrote: > --On August 8, 2013 4:34:32 PM +0100 Mark Cairney > <[email protected]> wrote: > > >>> back-bdb or back-hdb?
