Package: libjpeg Version: 6b Severity: minor
Hi, Playing around with the upstream libjpeg, it seems to me that decoding is about 15% faster when the library is compiled with -Os than with -O4. I think that's significant enough to consider mentioning, since jpeg can be the bottleneck in some programs. You would want to see if you can reproduce it on a variety of different hardware and with a variety of images though. Just thought you might be interested... (And no, I haven't actually looked at whether you have changed the default in the Debian package. But the djpeg that I've built with -O4 runs at exactly the same speed as the one from your package, so I'm guessing that you've not tried -Os.)
