I started TC 7.0.20 to 7.0.28 50 times each and did some trivial 
statistics on the tldScanTimes:

version avg     median  min     max

7.0.28  414.4   388     234     922

I don't see a regression for 7.0.28 here. There was a slowdown between 
22 and 23, but we got faster since then and are not far away from 22.

Rainer
