Web Software Architecture and Engineering – Life on the Bleeding Edge

I’m wondering if anyone has tried running ColdFusion with JRE 6 Update 14… If you look at the Update’s Release Notes you’ll see a couple interesting updates. There are two that caught my eye.

  • Optimization Using Escape Analysis

    The -XX:+DoEscapeAnalysis option
    directs HotSpot to look for objects that are created
    and referenced by a single thread within the scope of a method compilation.
    Allocation is omitted for such non-escaping objects, and their fields are treated as
    local variables, often residing in machine registers.
    Synchronization on non-escaping objects is also elided.

  • Garbage First (G1) Garbage Collector

    Garbage First, or G1, is a low pause, server style collector.
    G1’s primary advantages over the Concurrent Mark-Sweep (CMS) collector include
    incremental compaction, better predictability and ease of use.

Searching Scroogle on DoEscapeAnalysis returns lots of interesting information and I can see how it can be useful. Same goes for the G1 Garbage Collector. Any thoughts?

  1. i’ve been running it since it came out and i haven’t had any problems. since the jvm is so easy to upgrade and roll back if need be, i usually run cf on the newest versions the second they are available.

  2. Tony,

    Did you use those two new options?

    We have SSL certs, so its always harder to upgrade, as we have to upgrade the trusted certs everytime.

  3. to be honest, i don’t mess with any of the options since i never had a need to. i just keep them the way adobe set them. maybe if i needed to squeeze some performance out of my configuration i would, but for now the defaults that adobe has setup work good.
