QCustomPlot Discussion and Comments

X11 PerformancesReturn to overview


It's not related directly to QCP but my widget-based application (with QCP) is very very slow over SSH/X11.
Do you have any hints to improve this case please ?


To give more details, the application is a real time dashboard with a refresh period of 100ms.
There is one qcp widget which takes the full application size.

I tried with OpenGL and without but it seems that for QWidget (Qt5) it uses software rendering, so there is no improvement.

The replot call takes around 30ms when the application is launched locally and around 1.5s remotely over ssh/x11.
