Hi Vijaianand,

the number you've quotes is not that bad, but you should be able to achieve a 
better performance with four 1.6 GHz cores. Does everything run on this one 
machine, e.g. the IMS bench and the database?

I assume that the DB is the bottleneck in your configuration, try to use 
usrloc in db_mode=0 to test. Another possible issue can be DNS, try to use 
IPs instead names or a local dns cache.

Cheers,

Henning
