Got it thanks, you can certainly feel the difference :-)
my previous wget now gets an "expected" 11.1MB/s and eats about 25% CPU (which feels a bit on the high side)

One weird note though, I accidentally installed the 1806 uniprocessor i686 kernel, and when it booted it didn't see the SATA drives

ata1 is slow to respond, please be patient
ata1 failed to respond (30 secs)
scsi0 : ahci

http://adslpipe.co.uk/nosata.jpg it happened twice so no fluke.

I suppose the subsequent panic is justified given that it didn't see the disks, but why would it not see them? I rebooted back to 1805 smp i686 kernel, installed 1806 smp i686 kernel and now all is well, I can double check the uniprocessor result if required ...
