[ts-7000] Bizarely slow read times from SD cards on TS7300

["Yan Seiner" <>]

I've been working with a TS7300..  I'm getting pretty good write times
but incredibly slow read times.  Could someone shed some light on this?

First we write out the kernel:

:boot# dd if=vmlinuz of=/dev/sdcard0/disc0/part1
1363+1 records in
1363+1 records out
698180 bytes transferred in 3.010000 seconds (231953 bytes/sec)
:boot# sync

Then we read it back to see if we got it all

:boot# dd if=/dev/sdcard0/disc0/part1 of=vm.chk count=1363
1114+0 records in
1113+0 records out
569856 bytes transferred in 173.850000 seconds (3278 bytes/sec)

After 3 minutes I got impatient and hit ^C.  What could be causing
this?  I mean, my read times are 100 x slower than my write?????
