Symptoms

We've noticed severe performance degradation between our current DL580 G7s running Intel Xeon CPU E7-4870 processors and previous machines of the same model (with different processors) and even against DL580 G5 machines. We aren't able to explain what causes the performance difference at this time. It appears to affect all of our 22 boxes of this model running Solaris. We've tested the same model running Windows and don't see any issues. We see about half the performance on single-threaded tests using the Scimark2 benchmark. We've seen similar results with both the Java version of the test and the compiled C version.

We see the problem with Solaris 10 8/11 s10x_u10wos_17b patch Generic_147441-01, as well as the latest patch, Generic_150401-11.
