syntax-highlighting-performance

Test harness to compare various run-in-the-browser syntax highlighters.

Usage

• Enter a size cap (in bytes) as required, to limit the size of resources that are syntax highlighted.
• Check the syntax highlighters you want to test.
• Press one of the test buttons
  • Single resource test - to only highlight the selected resource (using all selected highlighters).
  • All resources test - to highlight all resources sequentially (using all selected highlighters).

Results

• postMessage time - The entire 'round-trip' time of the main window asking the IFRAME to do the syntax highlighting, and receiving a response from the IFRAME after the syntax highlighting has taken place.
• setup time - The time taken to setup the IFRAME for a given syntax highlighter. E.g. add required JS/CSS to the IFRAME.
• setText time - The time taken to set the resource text in the DOM element to be syntax highlighted.
• highlight time - The time taken for the given syntax highlighter to do its highlighting.
