How can I find out which backend I have installed? Backend performance,

[Ovanes Manucharyan <olm@csun.edu>]

I have installed openldap 1.2.9 many months ago and can't remember 
which backend is in use?

Can anyone tell me which backend is installed by default? Can I 
choose a different one for speed reasons?

I know that the commercial version of BDB2 can support better 
performance in some areas.. Would having the commercial version as 
opposed to the freeware version of bdb2 improve performance with 
openldap?
