HotSpot does not use 1G pages on amd processors that support them when running solaris. They should be used when appropriate to improve performance.
The Intel teams says:
'We received the JVM hotspot binary that support 1GB page size, very quick run of SJBB shows above 1.10x speedup!'
John, Can you please provide a target release & build? thanks.
Detect 1G pages on amd processors running solaris and use them when appropriate. See comments.
