I agree if you're using cffile or using cfinclude or the like. What I'm talking about is writing static files such as an html article. You only write and update the file in your admin. Unless you have a herd of people working on the file at once than there are few I/O processes that need to be done. > While I'm not advocating it, running purely with database queries > makes nearly as much sense (at least, up to a point) -- since both > ColdFusion and the database are caching the disk-based data into > memory.

For example I have an Intranet for lawyers that has 600,000 articles. There is no way I'm going to query the db every time one of those articles are accessed. First because they are long-winded and second because they are accessed frequently. > This thread is really turning into a discussion about the basic > tradeoff of relying on generic algorithms provided by the software > stack to optimize the amount of data in memory vs specific tuning and > optimization steps that are application specific... Agreed, it's a nice discussion to have every once and awhile. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:196297 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
