jdk8 build times

Fri Aug 30 08:50:00 UTC 2013

Hi Pete,

a very silly question but are you sure you are using the new build?
Maybe you can post your complete configure and make commands and your
environemnt?
Your build times really look like the ones from the old build. What
build times did you had for building jdk7 for example?

Regards,
Volker
