Yes it is several (2-5) seconds. Someone found the exact figure.
It would be good if it is more, say 20-30 seconds. Hard to say, if it may be changed. It may be hardwired or set in drivers that Onyx cannot modify....
It has been described here at least half year ago. Probably more. Once you know, you may avoid in most cases and if not the solution is at hand....
So, I take it as feature, not bug. But I would not mind if it is solved somehow.
