This is not a bug, SyntaxHighlight works just fine but we where optimizing our wiki to increase performance and found out during testing that SyntaxHighlight on its own adds +/- 0.5 seconds of loading time on a wiki page. The average load time for the Main Page with the "default content" after install goes from +/- 1.1 seconds to +/- 1.6 seconds when SyntaxHighlight is enabled. It probably depends on the hardware used. This was tested on a clean wiki with only SyntaxHighlight enabled. Tested with chromium with disabled browser cache. Is this normal behavior in combination with HHVM or is the SyntaxHighlight making HHVM unhappy with non "optimized" code? Has this anything to do with HHVM? Did not test it under Zend OPCache yet.
Tested on:
- Ubuntu Server 14.04 LTS
- Apache 2.4.7 (Ubuntu)
- PHP 5.5.9-lubuntu4.5 (cli)
- MW 1.24.1
- MySQL 5.5.41
- HHVM 3.5.0 (srv)
