Yes doclist compression is a must. Higher intersection throughput and less bandwidth stress. Are you loading your doclists from persistent storage? What is your current max rps?
I'm loading the data off a memory mapped SSD, trivial questions will probably be answered entirely from memory, although the disk-read performance doesn't seem terrible either.

It depends on the complexity of the request, and repeated retrievals are cached, so I'm not even sure there is a good answer to this.
