I'm pleased to announce the latest release of darcs-benchmark with some
nice backend work by Petr and a few UI tweaks from me.
With the Darcs-2.5 release getting closer and closer, we're going to
need a little more benchmarking help.
First: we're missing benchmarking numbers for Windows. Max has
volunteered a few of them, but there are holes because darcs-benchmark
was buggy at the time. Could I get a volunteer to flesh out our 2.5
benchmarks on Windows? Perhaps Max?
Second: it'd be nice to have some numbers comparing old-fashioned
repositories on Darcs 1.0.9 with hashed repositories in Darcs 2.5.
Nathan, would you be interested in repeating your experiments?
Third: If you have already provided us with benchmarks for 2.4.4 vs 2.5,
could you please upgrade darcs-benchmark and re-run darcs-benchmark
cabal install darcs-benchmark
There are some changes to how we report the results (mean => mean + sd,
and now graphs in front), and it would be great if all our benchmark
results were uniform. Note also the darcs-benchmark run --converge
feature below if you're interested in refining your numbers (getting rid
of the "~" and "?"s)
Fourth: if you have participated in darcs benchmarking, but not for this
release, please move away the contents of your ~/.darcs-benchmark
directory to avoid cluttering the report.
Changes in darcs-benchmark 0.1.9
* darcs binaries are now identified by a hash of darcs --exact-version
to avoid lumping together results from different mid-release darcs
* timings are now reported as mean + one standard deviation
* graphs are displayed before numbers
* new run --converge flag to runs benchmarks for which there is still
* support for hg/git variants of repositories (experimental, disabled
