Optimize processor consumption

[baxiry]

fyneterm consumes a lot of processor , and does not work smoothly on MacOS M1

Thanks

Can you confirm what commands were running in the terminals? Background CPU usage should be negligible.

Though it could be a duplicate of fyne-io/fyne#2506

[andydotxyz]

running in the terminals?

I was meaning what is happening inside the terminals? Or are they all idle?

[baxiry]

@andydotxyz oh sorry, all in all idle

[andydotxyz]

With the latest version this may be resolved - are you still having trouble @bashery ?

[baxiry]

There is a small improvement. I built it with Go 1.20

[andydotxyz]

You would still categorise the app as not working smoothly?

[baxiry]

Processes inside the shell run smoothly. Operations on window are still bad. Zoom in .. Zoom out Move the window ..

[andydotxyz]

Move the window ..

??? This should literally be a no-op!

Operations on window are still bad. Zoom in .. Zoom out

OK - this could be slow due to complete cache invalidation. Should we focus the bug report on just that or are other operations still too slow?

[baxiry]

Everything is good. Only the processor consumes a lot. For example, normal fyne applications consume 0.1 - 1% of the cpu when idle. But fyne-terminal consumes 15% of the cpu when idle.

Are you sure you are on latest version? I see idle around 3-4%. Not ideal but certainly not as bad as you report.

I built it from source with go1.21.0 The problem still exists.
