You're right of course. I was just a little worried about performance but
maybe that's not a problem. I'll have to do some experimentation. Thanks

Hmm, I'd say around 0.5 seconds and the state dump wouldn't be easily
noticeable by the players in an MMORPG-style game.

But in my own case streaming state changes to another DGD instance might
mean I don't have to do state dumps, or that I can do them on the backup
DGD instance and not bother players with the lag. I was just curious as
to whether it was possible to speed them up in case the streaming thing
wouldn't work as hoped.
