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.


The user guide is available from the [help] button and goes into more detail about each benchmark and its configurable parameters.
