Re: NetBSD/Xen samba performance low (compared to NetBSD/amd64)

I believe Samba is single threaded, so can't take advantage of multiple
CPUs for a single stream. I'm not a Xen expert, however I'm not sure
running this in Dom0 is a representative test. I imagine most workloads
would be done within a DomU, while Dom0 is just a control domain and
allocates CPU and memory resources, so you may have additional
overheads + latencies.
