coldfusion 64-bit - doesn't support standard edition
I've been running a Windows 2003 64-bit server for almost a year now. When I bought it, it didn't actually occur to me that coldfusion wouldn't support this. As it was, it was easy enough to get coldfusion 7 standard running with a little help from Ben's blog entry.
I've always assumed though that there must be some performance loss with this method. I therefore looked forward to the 64 bit support promised with coldfusion 8
The 64-bit windows support didn't come out until the recently released 801 updater. I bought an upgrade license, figured out how to get IIS back into 64-bit mode and installed coldfusion 801. All seemed to be ok, until I noticed coldfusion was running developer edition!
After some panicking, re-starting and re-installing, I eventually found out that coldfusion 8 Standard doesn't support 64-bit. I'm presuming there's no technical reason for this. The marketing genius at Adobe who came up with this licensing model, really needs to think again about this.
While I can see the reasoning behind the Enterprise Edition being for high-performance servers, determining this by 64 or 32 bit processors is a bit strange. A really fast multi-processor 32bit server will easily out-perform a crappy 64bit one.
I'm back running coldfusion 8 on IIS-32bit mode. It just seems such a shame I can't take advantage of the extra performance.

I hope Adobe get their act together for licensing CF9 when it comes out. Not only does the 32-bit restriction affect most people, but the 2-CPU limit affects a lot of VPSs. You could have a bottom of the range VPS, but it runs on 8-cpus, requiring 4 CF licenses!
