Very simple pattern takes forever

Hi, Years ago I ran into the problem of patterning a sketch and it took forever. The advice was to pattern a part
Now I try to make a 20x20 pattern and the performance is really slow. Is that normal?

The regeneration time is about 
3 minutes. It it a local machine problem or on the server side?

I am seeing 25s here:



Regeneration is all server side, so check the values again. 

Anyway for things like this, it is the boolean operation that takes the time. Please review my blog post to see some techniques for speeding things up: https://www.onshape.com/en/resource-center/tech-tips/tech-tip-how-to-create-faster-patterns-in-onshape

I'm sure I could make it faster

OK I was looking at the wrong Part Studio, but even so, the techniques are the same

Thanks @NeilCooke, so my 188 seconds of regeneration time was maybe because the server had a busy day? Today it gives 41 seconds if I change the tilecount from 20 to 22. Mind you if you don't change the parameters it obviously regenerates much faster. Well I did check the blog but cant see how to speed it up.  


If I skip the boolean cutout it gives 39 seconds.
If I try to make 100 tiles I think I should go for lunch ;-)
