Ok, there are at least four things to consider.

1) Mac vs. Win
2) Spec of the systems
3) How BiaB renders (in RAM or cached) vs how the Plugin renders (file-based)
4) DAWs

1) I don't think it is a Mac vs. Win issue (Need another Mac user to benchmark and suggest moving that to the Mac area to get more Mac users)
2) Your time BIAB Plugin: 27.959 seconds. vs mine 26.888 (basically the same so it is not your system or Mac vs Win)
3) The plugin has been and will continue to get tweaked to work the same in all DAWs. There are also some styles that will hang while rendering so it is important to always give test step specifics so others can verify and report the time benchmarks and hang issues to support so that they can track it down.
