Make 2D very very slow

unhandled

#1

Make 2D in V6 ((6.0.17172.1151, 21/06/2017) is very very slow on my computer:

A very simple test model of three entities takes 11.26 secs; in V5 the same model takes 3.48 secs….(timed via iphone stopwatch)

1.33 seconds here (command line report)… couple of hidden lines missed though. --Mitch

Yeah, less than two seconds here for 3rd Angle, and hidden lines, tangent edges; with scene silhouettes a wee bit longer, it seems, but less than three seconds - About the same in V5. Hmm - nothing comes to mind - Tony is this consistent or just special with these objects?

#4

Pascal - yeah, its consistently slower by quite a margin than V5.
It takes maybe 3 seconds for the dialog to even come up (in V5 its practically instant).

thanks

Hmmm - the dialog is different - @rajaa - this looks like Eto, right? Any idea what could slow that down?
Tony, can you paste the report from SystemInfo here?

thanks,

@curtisw do you have ideas about why Make2D dialog it taking long to load?


(Curtis Wensley) #8

Hey @rajaa, sorry I don’t. Eto shouldn’t be what is slowing things down here, creating UI is (typically) very fast.

If your view model triggers tons of property changes when first starting up it may exaggerate any slowness. Also, keep in mind any WPF UI will take a few seconds the first time it is shown in Rhino after Rhino is started. So, if say you run the Text command, then run Make2D for the first time and it isn’t slow to show the dialog, it’s WPF’s startup that may be adding to the problem there.

I would recommend running using the VS profiler to see if you can identify where the CPU cycles are going.

Well, things are looking up…

In (6.0.17178.4271, 27/06/2017) a test file (attached) takes 22.72 seconds in V6, and an astonishing 9 minutes 8 seconds in V5!

Both versions miss a few hidden lines…

Also, the make2D dialog is coming up in V6 in about a second, (v5 is instant) so that’s good enough for me…
