So as you can see I'm getting around 15M/s writes, as posted
originally... reads are up to 57M/s but a lot less than that in most
tests (in fact they are around the 20M/s as posted originally)...
anyway all I've asked for here is help in tweaking OpenBSD to get
somewhere near the speed of the SSD, but I'm going to assume this
isn't possible on a Soekris, thanks for your help all.
Unless someone is prepared to offer me advice in relation to the SSD
speed I'm done.
Thanks all.
