Nothing new, move along
Not surprising. I have been using in-order (Via up till recently) cpus for servers for 8 years now. They can run circles around a Xeon as long as you do not force them to do heavy computation.
By the way, Intel and AMD are actually better now than they used to be. The difference was truly staggering 8 years back.
In 2002 a Via C3 800 delivered with ease >= 60MB/s ext2 filesystem performance on a RAID 1 software set while consuming 7W (motherboard without disks). An OEM edition of an Intel Xeon 2x2 (2 cpus, 2 threads each) barely crawled at 20MB/s while consuming 200W+ (again motherboard only). That is more than 60 times difference not in Intel's favour. So looking at the graph there has been a considerable improvement in Intel's finest. However, it is still not good enough to beat an in-order CPU doing a simple IO-bound task.
