Pro vs. E02 - Some Benchmarks (4 replies)

I picked up a bricked E02 on eBay and was able to fix it with serial console. I thought it the appropriate time to compare the performance with my Pro. Here are some benchmarks for both devices using a Sandisk 16GB Ultra Fit 3.0 Flash Drive on both and then a 320gb 7200rpm Seagate 2.5 drive in Esata enclosure for the Pro:

I am not sure why the E02 is not doing as well as the Pro. I thought even overclocked the Pro would barely manage to reach an E02's sysbench . Wrong assumption? Maybe I am doing something wrong? Comments appreciated.

Also, if you wanna compare sysbench numbers to some more modern SOC's, look here: http://wiki.glidernet.org/cpu-boards
