I wonder if it possible to run the whole IDE from a RAMdisk, or at least use a RAMdisk for compiling. I see while compiling that there's a lot of reads and writes to HD
Of course, it wouldn't make much difference if the program is small. But I guess it could save a lot of compiling time when the sketch is a few thousand lines.
