Thanks, I tried upping maxElementsInMemory to greater than the number of subjects and it did reduce the number of LDAP queries, but overall it still took about 10 hours to provision.  It's not pushing our LDAP server very hard, so maybe increasing the LDAP pool size would help?

I think cache tuning is important.

Setting maxElementsInMemory to be greater than or equal to the number
of subjects should help reduce the number of subject source (ldap)
queries.

I would have to remember better, but setting logging to debug will
print out cache hit/miss statistics when running the psp from the
command line.
