Thinking about it fast filtering is more attractive as long as loading isn't to slow I suppose. It's quite annoying to wait 2 minutes for a file to load and >=2 minutes on every filter operation.Ya. It was quite surprising to me to find out how much data we're generating and throwing away on each dissection pass. Now I'm wondering how much of this could be alleviated somehow by a more efficient tree representation...
The answer is apparently lots :) I tweaked some things in r52568, r52569 and r52573 that had a fairly substantial improvement when dissecting with a tree. "tshark -V" is as much as 18% faster in my tests, and filtering should improve a little as well, though that is much harder to measure. This may or may not fix the complaints you've been getting, but it's a good improvement to have regardless.
