[Spice-devel] MOUSE rate down to 1/4 compare with bare metal PC, how to explain?

[Walter Mitty]

Hello guys,

I found if I turn off *agent-mouse* by the param: *agent-mouse=off*, the
mouse report rate can improve to 50% ~ 80% of the bare metal.
I'm still trying to make it as better as possible. If you have any
suggestions, please let me know.

Yours sincerely,
Walter
