The motherboard project is not very complex, I would say that
performance should be tolerable UP to that size complexity, if we set
the bar any lower, usability will suffer and people won't like KiCad
because it's sluggish and interface lag is the worst kind of lag.
My project isn't finished and Chris' project is available now, is just
the right complexity and has layout that can be used for testing as
well as a schematic.
*LG 5K 27" display running 3200x1800 (the highest resolution without
making text blurry, using this for work every day, so it's
extravagant, it's practical)*
*Actions:* pan with middle mouse, zoom back and forth.
*eeschema:*
Low Res - at least 2 times slower than would be considered normal, I
would have to guess ~400ms lag
Normal - 4-5x slower compared to low res mode ~1700ms lag
Even in low res mode, and removing 75% of the items from Chris'
schematic, the lag is still ~200-300ms, that's just not right.
Additionally, I filed https://bugs.launchpad.net/kicad/+bug/1753054
because the mouse zoom is screwed up in eeschema, coupled with the
lag, it's unusable. Maybe the pan lag is related to the zoom, maybe
there are multiple steps being rendered when it should just jump to
where the mouse ended up at, I don't know.
*pcbnew - **Normal Resolution:*
Accelerated: No-AA, <50ms
Fallback: 500-1000ms for panning, 300-600ms for zoom
Legacy: 1300-1700ms for panning, 600ms for zoom
Low Res mode: did not notice speed increase, except maybe Fallback was
~400ms faster.
I'm not saying halt the horses, certain modes are obviously limited,
ie Legacy and Fallback by the nature of the task presented, but
eeschema is barely displaying 10% of the content pcbnew is but lagging
so much worse!
Just thought I'd include rendering of the Accelerated Graphics (top to
bottom: Supersampling 4x, Subpixel AA (Ultra Quality), No AA)
All 3 modes are responsive, probably <50-100ms lag, I'd consider this
performance great, considering the amount of elements on screen.

How long should it take to delete this many selected elements in pcbnew?
Answer: about 50x too long! I think it was like 3mins, perhaps ESC key
should be available to press anytime to undo the delete action and
restore to pre-delete screen when accidental actions are triggered
that take forever to complete?

Hi,
to be honest, I don’t really know what this is about.
@Andrey:
You looked for a very complex (foreign) project (Chris mainboard?)
to prove that eeschema is slow on Mac?
Well, we know that and we told you already some weeks/months ago
why it is like it is (if memory serves me right).
Or, do you have an own project that is so ridiculously slow, that
you can’t work with it?
If so, please provide it so that we can analyse why this specific
project behaves like that.
If you can’t or don’t want to provide it we could tell you how to
do some performance measurements so that we might see something.
Obviously, there are a number of Mac users here and also over at
the KiCad forum who might also be happy to get some more
performance here and there, but who are in general reasonably able
to work on their projects (including myself, on a 2012 Retina
MacBook with only an i5).
Regards,
Bernhard

Maybe my schematic isn’t busy enough? I’m a fan of using more
smaller sheets with less info on each than one big sheet with
everything.
