I've removed half the memory, leaving 4Gb, and rebooted into "Solaris xVM", and re-tried under Dom0. Sadly, I still get a similar problem. With "dd if=/dev/zero of=myfile bs=16k count=150000" I get command returning in 15 seconds, and "zpool iostat 1 1000" shows 22 records with an IO rate of around 80M, then 209 records of 2.5M (pretty consistent), then the final 11 records climbing to 2.82, 3.29, 3.05, 3.32, 3.17, 3.20, 3.33, 4.41, 5.44, 8.11
