- Rust

hyperfine - v1.14.0

Add a new --output={null,pipe,inherit,<FILE>} option to control where the output of the benchmarked program is redirected (if at all), see #377 and #509 (@tavianator, originally suggested by @BurntSushi)
Add Emacs org-mode as a new export format, see #491 (@ppaulweber)
Relax glibc requirements, see #508 and #512 (@sharkdp)

- Rust
Published by sharkdp about 4 years ago

Features

Added a new --shell=none/-N option to disable the intermediate shell for executing the benchmarked commands. Hyperfine normally measures and subtracts the shell spawning time, but the intermediate shell always introduces a certain level of measurement noise. Using --shell=none/-N allows users to benchmark very fast commands (with a runtime on the order of a few milliseconds). See #336, #429, and #487 (@cipriancraciun and @sharkdp)
Added --setup/-s option that can be used to run make all or similar. It runs once per set of tests, like --cleanup/-c (@avar)
Added new plot_progression.py script to debug background interference effects.

Changes

Breaking change: the -s short option for --style is now used for the new --setup option.
The environment offset randomization is now also available on Windows, see #484

Other

Improved documentation and test coverage, cleaned up code base for future improvements.

- Rust
Published by sharkdp about 4 years ago

Features

--command-name can now take parameter names from --parameter-* options, see #351 and #391 (@silathdiir)
Exit codes (or signals) are now printed in cases of command failures, see #342 (@KaindlJulian)
Exit codes are now part of the JSON output, see #371 (@JordiChauzi)
Colorized output should now be enabled on Windows by default, see #427

Changes

When --export-* commands are used, result files are created before benchmark execution to fail early in case of, e.g., wrong permissions. See #306 (@s1ck).
When --export-* options are used, result files are written after each individual benchmark command instead of writing after all benchmarks have finished. See #306 (@s1ck).
Reduce number of shell startup time measurements from 200 to 50, generally speeding up benchmarks. See #378
User and system time are now in consistent time units, see #408 and #409 (@film42)

- Rust
Published by sharkdp over 4 years ago

Features

The -L/--parameter-list option can now be specified multiple times to evaluate all possible combinations of the listed parameters:

bash hyperfine -L number 1,2 -L letter a,b,c \ "echo {number}{letter}" \ "printf '%s\n' {number}{letter}" # runs 12 benchmarks: 2 commands (echo and printf) times 6 combinations of # the "letter" and "number" parameters

See: #253, #318 (@wchargin)

Add CLI option to identify a command with a custom name, see #326 (@scampi)

Changes

When parameters are used with --parameter-list or --parameter-scan, the JSON export format now contains a dictionary parameters instead of a single key parameter. See #253, #318.
The plot_parametrized.py script now infers the parameter name, and its --parameter-name argument has been deprecated. See #253, #318.

Bugfixes

Fix a bug in the outlier detection which would only detect "slow outliers" but not the fast ones (runs that are much faster than the rest of the benchmarking runs), see #329
Better error messages for very fast commands that would lead to inf/nan results in the relative speed comparison, see #319
Show error message if --warmup or --*runs arguments can not be parsed, see #337
Keep output colorized when the output is not interactive and --style=full or --style=color is used.

A few enhancements for the histogram plotting scripts and the advanced statistics script

hyperfine - v1.9.0

Features

The new --parameter-list <VAR> <VALUES> option can be used to run a parametrized benchmark on a user-specified list of values. This is similar to --parameter-scan <VAR> <MIN> <MAX>, but doesn't necessarily required numeric arguments.

bash hyperfine --parameter-list compiler "gcc,clang" \ "{compiler} -O2 main.cpp"

See: #227, #234 (@JuanPotato)

Added none as a possible choice for the --style option to run hyperfine without any output, see #193 (@knidarkness)
Added a few new scripts for plotting various types of benchmark results (https://github.com/sharkdp/hyperfine/tree/master/scripts)

Changes

The --prepare command is now also run during the warmup phase, see #182 (@sseemayer)
Better estimation of the remaining benchmark time due to an update of the indicatif crate.

Other

hyperfine is now available on NixOS, see #240 (@tuxinaut)

- Rust
Published by sharkdp over 6 years ago

hyperfine - v1.8.0

Features

The --prepare <CMD> option can now be specified multiple times to run specific preparation commands for each of the benchmarked programs:

bash hyperfine --prepare "make clean; git checkout master" "make" \ --prepare "make clean; git checkout feature" "make"

See: #216, #218 (@iamsauravsharma)

Added a new welch_ttest.py script to test whether or not the two benchmark results are the same, see #222 (@uetchy)
The Markdown export has been improved. The relative speed is now exported with a higher precision (see #208) and includes the standard deviation (see #225).

Other

Improved documentation for scripts folder (@matthieusb)

- Rust
Published by sharkdp over 6 years ago

hyperfine - v1.7.0

Features

For example, the following command runs sleep 0.3, sleep 0.5 and sleep 0.7: bash hyperfine --parameter-scan delay 0.3 0.7 -D 0.2 'sleep {delay}' For more details, see #184 (@piyushrungta25)
