Have you tested the difference between cold and warm FS caches on a project with a shitload of files? There's a reason why the core Linux devs love Intel SSDs!

Have you tested the difference between cold and warm FS caches on a project with a shitload of files? There's a reason why the core Linux devs love Intel SSDs! The reason that parallel make helps so much (especially with 2x more jobs than processors) is that you aren't idling while blocked for I/O, and are piling up the I/O queue higher so the scheduler can de-randomize some I/O (elevator algorithm FTW).
