Re: x5 Speed Increase on Server Side with Swift?
That article in the link you provided is an excellent analysis. The author of the benchmarks cited in the Reg story was comparing apples to oranges from multiple different perspectives.
I suspect the reason for this was benchmark author didn't really know much if anything about many of the frameworks he was "testing" and just googled some tutorial examples. The result was numbers that were measuring very different things in each case.
This is such a common problem that it might make for a good series of articles for El Reg to publish if they can get someone (or a series of people) to write it for them.
