I was experimenting with using non-1024 block sizes in ext2fs --
I tried 2048 and 4096. It seems that using non-1024 block sizes
creates a noticable slowdown. Is using this feature not supported,
or not tested? I was doing this on 2.0.29 and 2.0.30.

It's probably having a mix of 1KB and 4KB that's slowing you down. I use 4KB
block file systems exclusively because my tests show them performing better
than 1KB file systems, and I have more disk space to waste than CPU cycles.
