There is a peculiar report

that file operations are very slow.
That was apparently solved by switching opengl to software.
Could it be that some gui redrawing use opengl functions?

This is highly unusual, and probably specific to some interaction with your hardware.  Can you try Torsten's suggestion to see if there is another process consuming CPU resources.  This will also show whether the Octave process is using too many CPU cycles.

Thanks for the report. Could you please check with a process monitor or task manager is a process is draining cpu resources?

Everything is slow in 8.1.0. Keypress takes 3 seconds. Menu takes 15 seconds. But once it runs script it is same speed as 7.3.0.

Using 7.3.0 for now.

No 8.1.0 in bug list so picking Other.
