Recently (since last update or two, perhaps?), my phone that uses Rethink has been pretty slow at times to open pages - and pretty randomly, at that.
Trying to figure out what's going on, I looked in logcat. It has a lot of messages; I'm not sure which ones are relevant, but "spammy" sounds like a good target:
