Oh dear. I just attempted to use Ben Nadel's POUtility.cfc to create my excel spreadsheet.
Couple of problems. #1 - it took 141 seconds instead of 45 seconds. 3x longer. #2 - it used almost 500 MB of RAM. 2x more. #3 - it had less functionality - my method of producing the file as HTML tables gave me column specific CSS control over each cell. Advantages: #1 - file size, 27MB versus 84MB #2 - no warning for Office 2007 users Back at CFUNITED, I asked the Coldfusion product manager if they had any intention of improving the speed of string concatenation. I told him that I was doing a lot of string concatenation to manufacture excel files via HTML tables. He basically blew me off, saying I should be using POI for that. (If you're reading this, yes, I felt like you blew me off). Now, this might not be POI's problem.... maybe it has something to do with the POIUtility.cfc, but my initial results don't look good. :( -- Rick Root Check out CFMBB, BlogCFM, ImageCFC, ImapCFC, CFFM, and more at www.opensourcecf.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion is delivering applications solutions at at top companies around the world in government.
