> Could you please explain the experiment a little more?
Sure!

> How are you measuring read and write throughput?
C-Program, gettimeofday(). Very clean conditions: Empty flash, mount
JFFS2, fopen one file. Measure duration of fwrite(filesize). Throughput
= 1/duration.

> Which StrataFlash are you using?
E28F128J3, 128 Mbit. 128KiB erase block size.

> What board are you connecting the flash to?
Hynix HMS30C7202 evaluation board.

> What kernel and MTD are you using?
Kernel 2.6.11-hnx3
MTD/JFFS2 of kernel 2.6.11. (I know, I should try newest CVS...)
