Hm, I have also noticed very low performance when reading from
fat/vfat. For example, midnight commander takes a very long time
(about 10-20 seconds) to read a vfat directory with approx. 110 MB in
1400 files. I don't think, it's midnight commanders fault, because it
is way faster on ext2 partitions. Also, FAT isn't that slow. Norton
Commander (version 1.0 for win) takes about 1 - 2 seconds for the same
job under NT.

And, yes you're right. If I remember correctly, 1.2.x was much faster
on fat/vfat partitions.

BTW: I'am running 2.1.17.
