Recent release notes from Altium show they have changed defaults for DRC to
turn off text DRC checks.  Therefore, even if portions of the DRC slow down
the overall - it may be acceptable to turn off some of the DRC checks by
default.

Certainly, the aspire target would be to have a lightning-fast engine that
allows for all DRC checks to be enabled without any impact to performance.
However, based on competitive analysis - speed is not necessarily a highest
concern with respect to text and other classes of DRCs.

Regards,
Jason
