I would definitely recommend 64-bit. Not necessarily for reasons of pure performance (response time & throughput) but because you'll be able to use memory better, and caching things in memory is one of the ways you can significantly improve application performance. As far as cores vs clock speed, this will be very application-dependent. In short, it depends on what your application does and how it does it. CF is multithreaded, so more cores is better than fewer cores, all other things being equal. > How about SSD hard drives for local source code?

Unless your application does a lot of disk reads/writes (such as file uploads/downloads) this won't make much of a difference at all. Compiled CF files are cached in memory. > Does CF Enterprise make a big difference? Not unless you're using a feature specific to Enterprise. There are a bunch of features in Enterprise that either don't exist in Standard, or are "rate-limited" in Standard. PDF generation, for example, exists in both but performs significantly better in Enterprise. > Should we change the JVM to a faster one? What would that be? You should use the latest supported JVM for your version of CF, generally. That usually won't provide a speed increase, but will fix specific bugs in earlier JVMs. Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ http://training.figleaf.com/ Fig Leaf Software is a Veteran-Owned Small Business (VOSB) on GSA Schedule, and provides the highest caliber vendor-authorized instruction at our training centers, online, or onsite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
