Live Drill Table = Slow Performance

I'm currently working on a fairly complicated 16 layer design which has 3000+ vias.

This is a second spin due to feature creep.

Live Drill Table (3178 Driils)

I was experiencing very slow and sluggish performance while placing new vias, moving existing vias or deleting vias.

So the troubleshooting began:

At first I suspected active online DRC checking. After some further investigation I determined the sluggish performance was due to the Live Drill table.

Test:

Open any large design in Altium with a live Drill table, select the P then V key and start placing vias, there will be a long delay (~ 2 seconds) between the via placements.

Work around:  

Delete the Live Drill table.  Place the drill table after all routing is done.

Idea:

Stop updating the Live Drill Table if it is NOT visible.

Note: The managed release will fail to generate the fabrication outputs (Gerbers) if the drill table is missing (not placed) in the design.


That's It !
