x264
This is a simple test of the x264 H.264/AVC encoder run on the CPU (OpenCL support disabled). Learn more via the OpenBenchmarking.org test page.
ebizzy
This is a test of ebizzy, a program to generate workloads resembling web server workloads. Learn more via the OpenBenchmarking.org test page.
Redis
Apache Benchmark
This is a test of ab, which is the Apache benchmark program. This test profile measures how many requests per second a given system can sustain when carrying out 1,000,000 requests with 100 requests being carried out concurrently. 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.
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.
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 Linux Kernel Compilation
This test times how long it takes to build the Linux kernel. Learn more via the OpenBenchmarking.org test page.
