Benchmark: Sun T2000 vs. Dell 6850 in LDAP Authentication
A Sun Fire T2000 outperformed a Dell 6850 by a factor of 2.8. Even more interesting are the other comparisions n in the same article:
The Sun Fire™ T2000 server delivers over 2.8 times better LDAP authentication performance than the Dell PowerEdge™ 6850, even when you consider that the Sun system only had a 1.0 GHz processor whereas the T2000 normally comes with a 1.2 GHz processor.
The list price for the Sun Fire™ T2000 server is $7657 less than the list price for the Dell PowerEdge™ 6850 server, even when you consider that the price for the Sun system includes a faster CPU than the one that we were able to test.
The Dell PowerEdge™ 6850 requires twice as much rack space as the Sun Fire™ T2000 server.
The Dell PowerEdge™ 6850 consumes nearly 1.5 times as much power (measured in Watts) than the Sun Fire™ T2000 server when both systems are idle.
The Dell PowerEdge™ 6850 consumes 2.25 times as much power (measured in Watts) under load as the Sun Fire™ T2000 server, even with an optimistic estimate for the Dell system and a pessimistic estimate for the Sun system.
Or in short: You pay less for a more capable system, needing less space, cooling and power. Okay, beeing a directory server is a tailor-made job for the system. But nevertheless very impressive.
