RESULT: With compression, REISER4, absolutely SMASHED the other filesystems.
Oh dear.. Well first off how can I say this.. You just made me CHOKE on my coffee. Haha, you know, the only time I used reiserFS, it was a bad experience, eventually . So even if it is faster, its definitely not as proven or as reliable as something like EXT3. I personally wouldn't be surprised to see ReiserFS3 be removed from the Linux Kernel eventually. Because from my experience at least, and what I've heard from others, its really not that good.
