The database server portion of the SPECjAppServer2004 benchmarks are quite interesting. An 8-chip, 16-core, 1.9 GHz p5-570 supports 4,368.02 JOPS, and the single-chip, 8-core, 1.2 GHz T2000 supports 1,781.37 JOPS.<div>&nbsp;</div> Both of these DB servers are running IBM DB2.<div>&nbsp;</div> The IBM p5-570 requires 16 x 100 Value Units (VU) to license DB2 on the server. The result is 2.73 JOPS/VU. The Sun T2000 requires 8 x 30 VU to license DB2 on the server. The result is 7.42 JOPS/VU.<div>&nbsp;</div> From this I calculate the Sun UltraSPARC T1 is 2.72 times more cost effective running IBM DB2 than the IBM POWER5, just considering DB2 license costs.
