Performance Benchmarks

Hardware and software configuration for performance benchmarks:

  • MacBook Pro (Retina, 13-inch, Late 2013)
    • 2.6 GHz Intel Core i5
    • 16 GB 1600 MHz DDR3
  • macOS 10.14.6 (Mojave)
  • Browser: Chrome 76
  • Hookpad is loaded with Arcade Madness (demo song) at global zoom of 50% and horizontal zoom of 58% to provide a challenging use case.
  • All comparisons use Chrome performance profiler for benchmarking. Hookpad 2.6 is compared to Hookpad 2.5
  • Absolute performance data is likely better than shown below because of overhead with the profiler in Chrome.

3.1x Faster Drag-Selection (12.5 FPS vs. 4 FPS)

To perform this test, I drag-selected a melody and chord region in Arcade Madness and recorded frames per second (FPS) in chrome profiler

4.5x Faster Note Adding (29 notes per second vs. 6.7 notes per second)

To perform this test I held down the “1” key for five seconds to enter notes in rapid succession. macOS has a “Key Repeat” setting in System Preferences that I set to “Fast” to push Hookpad as much as possible.

  • In Hookpad 2.6.0, 158 notes are processed in real time over five seconds while holding down the “1” key.
  • In Hookpad 2.5.0, 152 notes are entered, but it takes 22.6 seconds to process the 5-second key-press event: 5 seconds while holding the “1” key plus 17.6 seconds of processing / painting after releasing the “1” key.

2.6X faster note editing (100 ms vs. 260 ms)

To perform this test a selected note was shifted by a scale degree with the up key.

2.5.0 (2019.06.21)
