Hmmm.. Something is amiss indeed. Looks like something bad happened over the last week or two. Check out the version from about a week ago and you should see the reported numbers. I'll take a look and see what the mater could be. Ranga Marden P. Marshall wrote: > First, great job on the stack! > > I've been doing some basic performance benchmarking of the latest > stack code.
