It makes me cringe a bit thinking about it. There are so many more things that could theoretically go wrong with a JIS strategy... but I guess it works fairly well -- It's about the only thing I think nobody's complained about yet. in time. Further, VB is not a compiled language; it is interpreted as well. Mind you, I haven't seriously used VB since a cgi project back in 1997 but I was under the impression it was an option to compile your VB code these days. I could easily be wrong though. Not that I guess it matters all that much, VB being a dead language now. --min __ Get the mailserver that powers this list at http://www.coolfusion.com FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
CFMX - Slow, why?
I have just finished upgrading my dev box to CFMX. After going through a number of issues (search engine friendly URLs, problems with the installer), I finally have working sites again - but the debug execution times are simply unacceptable. I have 20 apps on this box where every page execution was routinely 50 - 500 ms under 4.5 and 5.0. Under MX, just about every page takes upwards of 2,000 - 20,000(!) ms. I should note this is only the first load of a given page - subsequent loads are normal. Is there some really obvious thing I'm overlooking? Has anyone else had this experience? This is a Win2K box with 256MB RAM and a 650mhz processor. Again, under CF 5.0 everything ran like clockwork. And, does anyone know of a program to allow CFMX licenses to be downgraded to CF 5.0? I need UDF and such, but this MX stuff is turning out to be a headache, especially this first time page loads deal. __ This list and all House of Fusion resources hosted by CFHosting.com.

Re: CFMX - Slow, why?
I think the reason that you are seeing slow page loads for each page the first time it is displayed is that CFMX compiles the code before viewing. Here is some talk about it: http://hotwired.lycos.com/webmonkey/02/34/index3a_page3.html?tw=programming Stuck in the 5.0 world, I haven't hit this wall yet. But I have seen articles on how to precompile an entire directory. Do a goole search and you should find what you need. Note, it does not happen for every page load, but for the first page load after a cfm file is changed.

RE: CFMX - Slow, why?
Big deal. I can't tell the difference between 1 MS and 10,000 MS. The delay is there in the beginning because the code has to be compiled first.
