Bench-slice-size

Below benchmark tests probe queueimpl7 queue implementation with different internal slice sizes.

Tests

Format

  • Benchmark*N: benchmark the queueimpl7 with a internal slice size of N.

Example Tests

  • Benchmark*1: benchmark the queueimpl7 with a internal slice size of 1.
  • Benchmark*10: benchmark the queueimpl7 with a internal slice size of 10.
  • Benchmark*100: benchmark the queueimpl7 with a internal slice size of 100.

There are two distinct tests:

  • BenchmarkMaxFirstSliceSize: benchmark the size of the first created slice in the queue.
  • BenchmarkMaxSubsequentSliceSize: benchmark the size of all subsequent created slices in the queue.
