Hi all,
I am currently finalizing my material for the LDC DConf talk, and I
thought it would be nice to include a quick runtime performance
comparison between the different compilers, just to give the audience a
general sense of what to expect.
Thus, I am looking for benchmarks to use in the talk. Specifically, they
should:
- be open source, or at least source-available, so other people can
reproduce the results
- be *reasonably* self-contained, so that I don't have to spend three
hours setting up build dependencies
- be written mostly in D, I don't want to benchmark GCC
- work with DMD 2.061 or DMD 2.062
- run on Linux or OS X
[snip]
In the future – i.e. as soon as possible, but somebody has to actually
spend some time on setting things up –, we might also want to set up a
nightly tester with such benchmarks to track performance of the
different compilers over time. It's not as crucial for GDC and LDC as it
is for the upstream backend projects, but there are still quite a few
things to watch out for in druntime/Phobos and the LDC LLVM
optimizations specific to D.
Hopefully sometime soon benchmarks would become part of the auto-tester
framework.
P.S.: Juan Manuel Cabo's "avgtime" is a really, _really_ useful tool for
benchmarking whole programs and actually getting solid statistics out of
it. Let's add something similar as a library for more finely-grained use!
