Hackbench
This is a benchmark of Hackbench, a test of the Linux kernel scheduler. Learn more via the OpenBenchmarking.org test page.
Stress-NG
Stress-NG is a Linux stress tool developed by Colin King of Canonical. Learn more via the OpenBenchmarking.org test page.
Darktable
Darktable is an open-source photography / workflow application this will use any system-installed Darktable program or on Windows will automatically download the pre-built binary from the project. Learn more via the OpenBenchmarking.org test page.
GIMP
GIMP is an open-source image manipulaton program. This test profile will use the system-provided GIMP program otherwise on Windows relys upon a pre-packaged Windows binary from upstream GIMP.org. Learn more via the OpenBenchmarking.org test page.
LuaJIT
This test profile is a collection of Lua scripts/benchmarks run against a locally-built copy of LuaJIT upstream. Learn more via the OpenBenchmarking.org test page.
Flexible IO Tester
Fio is an advanced disk benchmark that depends upon the kernel's AIO access library. Learn more via the OpenBenchmarking.org test page.
Timed Apache Compilation
This test times how long it takes to build the Apache HTTP Server. Learn more via the OpenBenchmarking.org test page.
Timed PHP Compilation
This test times how long it takes to build PHP 5 with the Zend engine. Learn more via the OpenBenchmarking.org test page.
Timed Linux Kernel Compilation
This test times how long it takes to build the Linux kernel. Learn more via the OpenBenchmarking.org test page.
x265
This is a simple test of the x265 encoder run on the CPU with a sample video file. Learn more via the OpenBenchmarking.org test page.
TTSIOD 3D Renderer
A portable GPL 3D software renderer that supports OpenMP and Intel Threading Building Blocks with many different rendering modes. This version does not use OpenGL but is entirely CPU/software based. Learn more via the OpenBenchmarking.org test page.
IndigoBench
This is a test of Indigo Renderer's IndigoBench benchmark. Learn more via the OpenBenchmarking.org test page.
NGINX Benchmark
This is a test of ab, which is the Apache Benchmark program running against nginx. This test profile measures how many requests per second a given system can sustain when carrying out 2,000,000 requests with 500 requests being carried out concurrently. Learn more via the OpenBenchmarking.org test page.
Apache Siege
This is a test of the Apache web server performance being facilitated by the Siege web serverb enchmark program. Learn more via the OpenBenchmarking.org test page.
Redis
Redis is an open-source data structure server. Learn more via the OpenBenchmarking.org test page.
SQLite
This is a simple benchmark of SQLite. At present this test profile just measures the time to perform a pre-defined number of insertions on an indexed database. Learn more via the OpenBenchmarking.org test page.
PostgreSQL pgbench
This is a simple benchmark of PostgreSQL using pgbench. Learn more via the OpenBenchmarking.org test page.
Git
This test measures the time needed to carry out some sample Git operations on an example, static repository that happens to be a copy of the GNOME GTK tool-kit repository. Learn more via the OpenBenchmarking.org test page.
