Is Intel Atom 270 really so slow?

[MK]

Thanks for help. I found that hw.setperf was 0.
After I changed it to 100 I have finally better result:

aes-128-cbc      18856.53k    23989.65k    25833.94k    26151.91k 
26475.44k
aes-256-cbc      14547.03k    16952.78k    18680.72k    18961.58k 
19041.28k

hw.cpuspeed=1600
hw.setperf=100
