Exchange Server 2007 SP1 Hub transport throughput with different message sizes

Large message size: effect of transport database cache size on throughput.

Background

Recently one of our support engineers came to us requesting performance data for a client deploying Exchange 2007 SP1 (E2K7 from now on).

The client wanted to know what level of steady state throughput was achievable by a Hub Transport server receiving 4 widely different average message sizes:

  • 25KB
  • 1MB
  • 5MB
  • 10MB

We had some of the data but needed to complete the table, so we employed the test bed used to measure transport performance for E2K7 and E2K7 SP1.
