if you are brave enaugh, you can give my rebuilds of the pre-ept kvm builds against an much more up2date smartos a try. i whouldnt be surprised if the performance difference is fixed than. http://mirror.jgotteswinter.com/smartos-builds/amd-pre-ept/20150613/ (if wanted/needed, sourcetree is on github) your transferrates are from within a kvm guest? a zone? global zone?
