Speed difference between EA versions and official distributions.

I hope this is the correct place to ask. Recently I tested our Java speech
recognition engine speed with several Java versions.
Two JDK 8 EA builds ( 1.8.0-ea-b109 and 1.8.0_20-ea-b19 )
One Stable Oracle JDK 8 release: ( 1.8.0_05-b13 )
One Stable Open JDK 7 release: ( IcedTea 7u55-2.4.7 )
And I observed that both Java-8 EA versions runs %6-8 faster than the
stable Oracle JDK 8 and Open JDK 7 releases. What can be the reason? Do EA
builds and Oracle official releases use different compilers? Or is there
something else I should be checking? What do you suggest?
Environment: Ubuntu 12.04 64-bit, Intel i7-3770 3.4Ghz x 8
