Lbench can make the following measurements
- integer-32 and floating-64 arithmetic performance
- performance of a few engineering functions (sqrt, sin, etc.)
- memory performance for cache memory and main memory
- time overhead to acquire and release a mutex lock
- time overhead to start and complete a process thread
- time overhead to start and complete a sub-process
- time overhead to call and return from a function
- disk I/O throughput for various record and file sizes
- All of these functions can be run with 1-9 parallel threads.
DocumentationThe user guide is available from the [help] button and goes into more detail about each benchmark and its configurable parameters.
