See? I can pull numbers out of thin air, too. Saying "an Intel benchmark" without qualifying the what and the how is completely useless.
You've got to be kidding. Have you ever *used* EXT4? It is so much faster than EXT3 that it's not funny.4. ext4 not hot
True. ZFS is hot. And BTRFS is hot (because it is a copy of something hot: ZFS)
If there's one kernel changed that has improved my day-to-day experience, this is EXT4. It's improved my compile times to the point they are almost indistinguishable from a ramdisk. Applications like Firefox and Evolution start up significantly faster. Boot times and fsck times are much, *much* shorter.
ZFS may be "hot" but it's certainly no speed demon.
Now you are just plain trolling.5. Linux just copies and never invents new smoking hot tech.
Please remind us, why are you even using Linux on the first place?
