a somewhat common case whereby two or more fields share a fair number of common analysis steps.
Right.
For the smaller token counts, any performance difference is negligible. However, even at 500 tokens, one starts to see a difference. The first thing to note is that TeeTokenFilter (TTF) is much _slower_ in the case that all tokens are siphoned off (X = 1). I believe the reason is the cost of Token.clone()
I might be missing something here, but why do you clone? I usually fill a List<Token> with the same instances and then only clone the tokens I need to update. The same token instances are used in multiple fields and queries at the same time and I never had any problems with that. Should I be expecting some?
