Not much, about 20 including all objects (it is a test setup), and it
have almost no load at all, about 1 to 10 requests per minute (just
me, testing stuff).
I used to have:
index default eq
in my slapd conf, in addition to the indexes for other fields, like:
index gecos eq,sub,approx
index phpgwContactOwner pres,eq,sub
index uidNumber,gidNumber pres,eq
but I removed the index default eq just to test... off
course, it didnd worked (as I suspected).
