How well does Sync Framework 4 scale?

I've had a little experience with sync 2 and found that it performed terribly for even relatively small datasets (5000 rows or so). I'm coming up to a new project and since the 4.0 CTP is out I was wondering if anyone had any luck with it.

I have a fairly large DB to sync开发者_运维技巧 (50 + tables with upto around 100,000 rows each). Before I head down the road of testing it I thought I'd reach out to the community and see if anyone has tried something similar.


Sync Fx v4 is mostly around supporting Silverlight, Windows Phone 7 and other devices. It still uses Sync Fx v2.1 under the hood. unfortunately, they've postponed the release and will release some part of the CTP as code samples instead.

am not sure which providers you used with v2, but the 2.1 release includes bulk procedures using TVPs and this coupled with the use of DatasetSurrogate improves the memory usage and performance compared with prior releases.
