It's not ideal, but one flow I end up using at some points is tmux-as-grep. Basically, something either gets dumped to terminal, and I use tmux's search. So then, for a combo of reasons (some good, some bad) I cat files to terminal on occasion, and I use tmux's search to find something in it.
The idea isn't that the I'm processing at the throughput rate of the emulator - it's more that a low throughput rate delays when I can start actually looking for something useful.
