yes, I pruned a little aggressively.
yes, he implies it doesn't matter to him. My point is it probably
matters to him more than he realises:-)
In my reading up on the topic, I found someone mentioned that it would
be good to have a benchmark. Someone else poopooed the idea. I'd like to
support the idea of a kind of benchmark.
A while back, I worked on some IBM software, including its PL/I
compiler. One of my tasks was to run some testcases. Some of these
testcases dated back around thirty years! Mostly, they were to ensure
conformance to some documented standards and to verify bugs fixed before
were still fixed. As you might expect on reflection, sometimes a failure
was a success (the program was expected to fail), and often the output
varied from one run to another (eg time/date on listings).
Unexpected results had to be examined, explained and maybe fixed.
Running such a test suite on PERL makes sense (and is probably done).
One of the outcomes that needs to be measured and explained is the time
(and other resources) it takes to run the tests, and how it compares
with expectations. In this case, measuring the time and resources
would/should have identified the problem.
Arguably, this should be done/monitored by Red Hat.

You cannot reply off-list:-)
