That really depends on the VPN. A good VPN with quality servers and good bandwidth into and out of their endpoints won't cause any appreciable bottleneck. A cheap VPN with low in/out bandwidth on their endpoints will slow things down significantly.
Personally, I use VyprVPN using their Chameleon protocol when I'm in China... it's the one my company IT recommends for employees travelling to China, and I've never had an issue with that being blocked by the GFW.
