I've read elsewhere that loading a compiler's include files, or frequently referenced documentation, or an emulators's file system, into a ramdisk would significantly improve performance. That's not true? Thanks, BTW, (to you and others) for the quick responses. --Eric House PS /usr/src/linux/Documentation/ramdisk.txt does not talk about using ramdisks in any context other than for creating boot floppies. I guess that's because they're pretty much useless otherwise?
