Saving Gh files is now taking a very long time

In the past couple of days I am experiencing a serious and strange problem.
When I am saving my gf definition is taking a long time, it used to take 1-2 seconds. Now it takes minutes…
Recently I have updated both my Rhino 6 as well as my Windows 10. Obviously one of the two updates or both are causing the problems.

I am also experiencing much longer times to get into my Clusters. Not sure if this a related issue.

Am I alone in this?

sorry all, for some reason the problem fixed itself.
