I configured a RAM disk on a Virtual PC running ArcGIS Desktop 10 and set my HKCU\Software\ESRI\Output\TempPath to a directory on the RAM disk. It’s hard to perceive any sort improvement with that sort of configuration and I’m curious to know if anyone else has done this on a non-virtual computer and what the results were.
Anecdotal answers are fine.
Also, putting the cache path on a ram disk is probably not a good idea, but is anyone doing this anyway? (HKCU\Software\ESRI\Desktop10.0\Settings\Cache Path)
