While a dual core CPU might not help much with Delphi alone, it will indirectly help by helping with other things like I/O and running all those other applications that inevitably run on a programmer's computer. My list of stuff that's competing for CPU power is fairly long and it doesn't even include a media player! > If you system is clean the other processes (all except Delphi) should > take [together] lees than 1% of your CPU.

That's because I don't think you can find new 32-bit-only CPU's those days and because both AMD's and Intel's top processor families are multi-core. An 32-bit-only single core new processor is a laptop processor OR a budget processor. Also I'd include some other items in the "upgrade" list: At the top of the list is RAM, second is a FAST hard drive (I'm thinking 10000 rpm here). And to the original poster: Also look for large DFM files in your project. Saving those large DFM files can take a really, really long time. If you find such a beast it probably contains a lot of stuff that can better be left outside the exe (ex: data in TJvData containers, large images in TImage containers). Try moving the data outside the exe and everything will be simpler. -- Cosmin Prund _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
