Stop using back-hdb, it's signficantly slower than back-mdb.  If you're 
going to insist on using back-hdb, then you *must* have a well tuned 
DB_CONFIG before you import.

For any backend, ensure you have tool-threads set appropriately (For 
back-mdb, values > 2 are ignored).

Use the -q flag if you know the LDIF is good.

slapadd has been heavily profiled and tested.
