Herbie, > before I changed to "Profiler" I was thinking about > the same as you do now but things are rather strange.... Could you prove/illustrate the implicit claim that TICKCOUNT used to measure program speed over intervals of several seconds is unreliable? What about a stopwatch or a wall clock?! It is quite conceivable that an oldfashioned benckmark of the sort I posted is gradually becoming meaningless because the current multitiered RAM structure gives them unrealistically fast RAM or just plain unpredictable RAM service. But, before swallowing such a bitter pill, I would like to see some hard evidence. Have you encountered important speed differences between stack variables and global variables? Incidentally, some description of the modus operandi of Profiler would be both helpful and confidence-inspiring. Cheers Laurent S
