We need time to investigate the performance regressions we're seeing and meanwhile we will keep tiered compilation default off.

7159766: Tiered compilation causes performance regressions Summary: Disable tiered in 7u4 because of the performance anomalies with Oracle FMW Reviewed-by: never, kvn ! src/cpu/sparc/vm/c2globalssparc.hpp ! src/cpu/x86/vm/c2globalsx86.hpp I thought this change was meant just for jdk7u4, but it seems like it has gone to jdk7u6 too: http://download.java.net/jdk7u6/changes/jdk7u6-b07.html Is that intentional? Best, Ismael
