Yes, ext4 is relatively new, modern, and benchmarks prove it to be fast.
NTFS is not so slow when used with Windows (7) but the linux ntfs-3g driver
is a lazy one. The ntfs (no 3g) driver is faster but it's read only.
The other problem with ntfs-3g is that it seems to me that sometimes it
corrupts the filesystem in a way that Windows (XP) has problems using it
("Delayed write failed" errors).
Also, some filesystems are less, some are more CPU-intensive so they work
slower when the CPU is busy with other things, but in this case, I think,
it's not about the CPU.
BTW, thanks for pulling my attention to this, now ext4 is mature enough that
I migrate from xfs...!
