There is simple way to improve filter performance in some cases with multiple
packets. Don't know why is not implemented yet.
1. apply any filter and save LIST of displayed packet numbers.
2. if next filter contains previous with conjunction (and) then search match in
the LIST+new packets.
2.1 if next filter contains previous with disjunction (or) then exclude from
search the LIST.
2.2 Similarly, in the reverse order.
You can update the lists.
