SELECT delitel(1000000, 1);
Mean times over the last five of six runs on my poor 500MHz FreeBSD
4.11-PRERELEASE box:
6741 ms 7.4.6 (from FreeBSD ports collection)
14427 ms 8.0.0rc5 (from CVS source)
I remembered that I had build 8.0.0rc5 with --enable-debug so I
rebuilt it without that option, not sure if that would make a
difference. The mean time increased by 8% to 15580 ms, which was
opposite from what I expected. I re-ran the 7.4.6 tests and they
came out the same as they had before.
I'm not sure what optimization flags (if any) the ports build of
7.4.6 might have used. I can take a closer look if you think it
matters.
