just to throw in my bit ;) the original post said the "slow" code executed in 811 milliseconds (0.811 seconds) and the fast code in 370 milliseconds (0.37 seconds).
If there are 1000 page views that is 811 seconds to execute the old code and 370 to execute the new, a saving of 441 seconds (7 minutes & 21 seconds) of processing time, even if this was the only page on the site that could produce a saving and only half the visitors to the site visited it only once, it is clear to see that on a high volume site some substantial savings can be made. -- Jay [EMAIL PROTECTED] "Computer games don't affect kids, I mean if Pac Man affected us as kids, we'd all be running around in darkened rooms, munching pills and listening to repetitive music..." ----- Original Message ----- From: "Jon Hall" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Friday, August 16, 2002 9:52 AM Subject: Re: Best Practices > So one iteration of the former executes in .811 milliseconds and the > latter .37 milliseconds?
