Which is at the moment slightly (10-20%) slower than ext2 but has a lot of other advantages. The only problem is the 2GB limit with an 32Bit integer on x86. Well I understand that we can't move generally to 8byte off_t types. Cause an old i386 would go down in pain. But is there no way to use such a 8byte value by accessing such large files?
