How can I speed up a slow VPN connection?

I've set up an OpenVPN VPN on an overseas server as a way of getting around the Great Firewall of China. It's working, but is considerably slower than paid services like Witopia. I'm a total n00b when it comes to this sort of thing and am wondering if the speed issues are a result of the configuration, or if it's just the way things are.
So: I set up the VPN using this walkthrough
. From looking around online, it appears that there are ways of fine-tuning an OpenVPN setup to make it faster, but I'm not neckbeardy enough to understand them, and am nervous about screwing things up by tinkering around too much with things I don't understand. I tried disabling LZO compression, since a couple of pages mentioned that it could have an impact on speed, but it didn't seem to make much difference -- I got about 0.16 Mbps either way according to various bandwidth test sites.
So this is kind of a two-part question, I guess: what, if anything, can I do to speed up this connection? And: I've read that IPSec is faster than OpenVPN, but at a glance it appears to be considerably tougher to set up. Are any speed gains from switching from IPSec to OpenVPN likely to be worth the hassle?
