0.2.0
Usability
: Simplify and organize the documentation and user APIs.
Functionality
:
- Add measurement and reporting of more performance counters on
Unices (collected via getrusage) for example page faults, user time, system
time and rss are now available in verbose mode.
- Re-enable CSV analysis with the same output format as criterion (
--csv
)
- Add CSV measurement dumping with
--csvraw
Control
: Provide better control over measurement process with
--min-samples
, --min-duration
and --include-first-iter
flags.
Speed:
Add --quick
flag that provides results much faster (10x) without
using statistical analysis.
- Reliability:
- Fix a bug in GC stats collection and reporting with GHC 8.2 that caused
incorrect reporting of some GC stats.
- Fix a bug in statistical regression that caused incorrect reporting of mean
and other stats.
- Improve reliability by isolating benchmarks from one another using the
--measure-with
flag. The results of one benchmark are no longer affected
by other benchmarks because each benchmark runs in a separate process.
- Introduce an optional value type
Optional
with an efficient runtime
representation to replace the ad-hoc fromXXX functions and the untyped
approach.
- Modularity:
- Introduce
--measure-only
flag that allows just measurement and no
analysis or reporting.
- Provide modular build, measurement code is cleanly separated from
statistical analysis code. As a result a leaner version can now be built
without analysis code (controlled by the
analysis
build flag).
