    Best guesses:

    - the small changes involved correction of major errors; if such errors caused a lot of logic gates to be unconnected or ininfluent on output behaviou, then a relevant part of the design was trimmed during logic synthesis and you actually had a smaller design than expected

    - you enabled Time Driven Synthesis or any other optimization feature in project settings

    - your machine has somehow become slower :-)
