Hi,
I'm using an old Pentium 3 dual CPU system with 4GB memory as my NAS box, and performance seems to have gone down after updating to FreeBSD 10 from 8.2. I have four 1.5TB disks in raidz1, and write performance with dd used to be about 50-60MB/s. Now it's about 40MB/s. Also, read performance over network has gone down. Earlier I got something like 60MB/s over Samba, and now only 40MB/s.. However, read speeds with dd seem to be close to 100MB/s (with /dev/null as output). Any ideas where to look at to get performance to previous level without investing in new hardware?
Also, when reading over network, CPU seems to be 40-50% idle.
