Updating a shape takes forever

Fredda

I have a GND shape, covering the entire top plane, which is giving me a headache. Manually updating the shape or any other edit that indirectly updates the shape takes forever. Well, it takes at least between 30 and 60 seconds and Allegro becomes unresponsive during that time. Allegro even shows as Not Responding in Windows Task Manager.

What can cause this behavior? I suspect that there's some setting in Allegro somewhere that should be changed.

I'm using Allegro 17.2 and Windows 10. Computer has an Intel Xeon E3-1505M v6 @ 3.00GHz CPU and  has 32 GB RAM so it should be fast enough.

It's a medium sized board as shown below.

    Hi, a good place to look first would be to see if there is anything wrong with your database. Under Tools there is a database check utility that you can run. There is also a performance adviser in that utility that can give insight into how the performance of this particular board is. Generally speaking in a board file things like lots of net rules can cause bottle necks. 17.2 on win 10 runs pretty good for me though it not as fast as 16.6.

    What service pack are you running there ?. "Allegro - Help About".  In 17.2 there is a a couple of user preferences. Under Display you would want to verify that OpenGl is not disabled. There is also an option that adds a shape visibility box to the "Visibility pane" for your layers where by you can turn off/on the shapes. The shapes will get drawn as an outline when that option is checked in the visibility pane. Doing that may increase the
    speed at which a shape can update. Perhaps you can try it.

    All the best.
