Property inheritance is off. I think it's probably due to the number of
lines in my org-files that are in org-agenda-files. These org files
(and yes I archive them... :) currently have 10522 lines totalling
551623 bytes...

Thanks! That's much faster.

Headlines with TAGS match:
-Effort="0:10"-Effort="0:30"-Effort="1:00"-Effort="2:00"-Effort="3:00"-Effort="4:00"-Effort="5:00"-Effort="6:00"-Effort="7:00"-Effort="8:00"/NEXT
6-7 seconds

Headlines with TAGS match: Effort={^$}/NEXT
6-7 seconds
---
Headlines with TAGS match:
-Effort="0:10"-Effort="0:30"-Effort="1:00"-Effort="2:00"-Effort="3:00"-Effort="4:00"-Effort="5:00"-Effort="6:00"-Effort="7:00"-Effort="8:00"/!NEXT
1-2 seconds
---
Headlines with TAGS match: Effort={^$}/!NEXT
1-2 seconds
I'll use the last one -- Thanks!

Yes... but that's why it's so useful -- development is mostly driven by
real world problems and needs and not some theoretical "Wouldn't it be
nice to have this cool feature" requests.
