We use on this system 64GB RAM. If you increase the block size in fio you should see
better throughput, as you already found. Cool, you sorted out the thing.
As a side note: interesting for us, was to discover that system usage between Debian 7
and FreeBSD was kind of different for our test workloads. Strange Linux system was
around 3-4% system time, no matter what sort of block size or number of files we were pushing
using hardware raid 10, resulting in a high iowait time and high run queue length (which on Linux
systems adds to it the iowait).
FreeBSD, I think, does not add to the run queue length the iowait processes waiting for a
storage, network etc. Is this correct ?
