Sun released a few days ago an update to their JRE version 6 update 10.  This update is of special interest to the ColdFusion community because it solves a renown bug when class loading cfc's. Usual behaviors for this bug on previous JDK 6.X was incredible slow performance on loading a highly used CFC application.  I just updated my servers to use the new 10 update and everything flies!  I highly recommend that you update your servers to use JDK 6 update 10.  You can download the bits from here:
