Yup, and it’s working fantastic! Thanks again John for developing this tool!

I assume you start SPJS from a console. Can you open another console and run ‘top’ and report CPU stats while CP is hard at work?

For example, I just ran the CP logo GCode on my Shapeoko2 run from my HPDV7t Quad i7 laptop (not ‘older’ by my definition).
I am actually surprised by the load (all GUI settings are CP defaults)

Sorry, sort of hard to read on this community GUI. Chrome eating a lot of cpu (71.10 + 17.28) %.

This is openSUSE 64bit/KDE

I believe you are correct Jarret, and I believe what were are seeing is 3 separate Chrome Threads (2 x 4 = 8 total threads available) so one thread is 71% consumed, I’ll guess the one running WebGL.
1 thread at 100% would be 12.5% of CPU, 87.5% * 12.5* = ~10.9% rough round numbers for total CPU.

I’ll give that a go next run. openSUSE has both GUI and CLI utilization monitors galore; ‘top’ is sort of the universal default tool.
It will be interesting to see how well a laptop/computer performs when the Thread utilization gets in the high 90%s; does it play catchup gracefully or crash? I have several ‘older’ candidates in the pile in the corner, will try them sometime.

I’ll check on mine tonight to see how it does. I did crank the rendering down to 10 fps but I’ll try it at 30 as well. 30 didn’t seem to bog the machine down at all but it’ll be interesting to measure.

I agree, 10fps vs 30fps stats will be very interesting.Post your CPU stats as well.
