Crowd Sourced System Benchmarks

Benchmark your CPU and compare against other CPUs. Also provides functions for obtaining system specifications, such as RAM, CPU type, and R version.

R benchmarking made easy. The package contains a number of benchmarks, heavily based on the benchmarks at, for assessing the speed of your system.


A straightforward way of speeding up your analysis is to buy a better computer. Modern desktops are relatively cheap, especially compared to user time. However, it isn’t clear if upgrading your computing is worth the cost. The benchmarkme package provides a set of benchmarks to help quantify your system. More importantly, it allows you to compare your timings with other systems.


The package is on CRAN and can be installed in the usual way


There are two groups of benchmarks:

  • benchmark_std(): this benchmarks numerical operations such as loops and matrix operations. The benchmark comprises of three separate benchmarks: prog, matrix_fun, and matrix_cal.
  • benchmark_io(): this benchmarks reading and writing a 5 / 50, MB csv file.

The benchmark_std() function

This benchmarks numerical operations such as loops and matrix operations. This benchmark comprises of three separate benchmarks: prog, matrix_fun, and matrix_cal. If you have less than 3GB of RAM (run get_ram() to find out how much is available on your system), then you should kill any memory hungry applications, e.g. firefox, and set runs = 1 as an argument.

To benchmark your system, use

## Increase runs if you have a higher spec machine
res = benchmark_std(runs = 3)

and upload your results

## You can control exactly what is uploaded. See details below.

You can compare your results to other users via


The benchmark_io() function

This function benchmarks reading and writing a 5MB or 50MB (if you have less than 4GB of RAM, reduce the number of runs to 1). Run the benchmark using

res_io = benchmark_io(runs = 3)

By default the files are written to a temporary directory generated


which depends on the value of


You can alter this to via the tmpdir argument. This is useful for comparing hard drive access to a network drive.

res_io = benchmark_io(tmpdir = "some_other_directory")

Parallel benchmarks

The benchmark functions above have a parallel option - just simply specify the number of cores you want to test. For example to test using four cores

res_io = benchmark_std(runs = 3, cores = 4)

Previous versions of the package

This package was started around 2015. However, multiple changes in the byte compiler over the last few years, has made it very difficult to use previous results. So we have to start from scratch.

The previous data can be obtained via

data(past_results, package = "benchmarkmeData")

Machine specs

The package has a few useful functions for extracting system specs:

  • RAM: get_ram()
  • CPUs: get_cpu()
  • BLAS library: get_linear_algebra()
  • Is byte compiling enabled: get_byte_compiler()
  • General platform info: get_platform_info()
  • R version: get_r_version()

The above functions have been tested on a number of systems. If they don’t work on your system, please raise GitHub issue.

Uploaded data sets

A summary of the uploaded data sets is available in the benchmarkmeData package

data(past_results_v2, package = "benchmarkmeData")

A column of this data set, contains the unique identifier returned by the upload_results() function.

What’s uploaded

Two objects are uploaded:

  1. Your benchmarks from benchmark_std or benchmark_io;
  2. A summary of your system information (get_sys_details()).

The get_sys_details() returns:

  • get_platform_info();
  • get_r_version();
  • get_ram();
  • get_cpu();
  • get_byte_compiler();
  • get_linear_algebra();
  • installed.packages();
  • Sys.getlocale();
  • The benchmarkme version number;
  • Unique ID - used to extract results;
  • The current date.

The function does include the user and nodenames. In the public release of the data, this information will be removed. If you don’t wish to upload certain information, just set the corresponding argument, i.e.

upload_results(res, args = list(sys_info = FALSE))
