Display statistics and Save log on Tiled builds

I just did a tiled build which took about 300 minutes. I had hoped the statistics window would keep open so I could save a build log and compare the stats to a new computer I’m building this coming week.
Unfortunately the statistics window disappear and there’s no automatic save of a log file anywhere. :evil:
I’d REALLY like to know the exact timing of different devices and macros so I could see where the new computer improves over my current computer.
