Adobe recently released a
performance brief claiming ColdFusion 9 is 40% faster than ColdFusion 8. While that number looks really good at first glance,
Marc Ackermann was kind enough to point out that they were running ColdFusion 8 using the 1.6.0_04 version of Java, which has a
known class loader bug.
While I don't doubt that ColdFusion 9 is faster than ColdFusion 8, I don't trust any of the numbers from the performance brief, especially a 700% improvement in CFC object creation.
