Limits higher than 10000/sec

Hi all. I currently have an iptables rule like follows in the raw table:

-A PREROUTING -p tcp --dport 1234 --syn -m limit --limit 10000/sec
--limit-burst 10000 -j ACCEPT
-A PREROUTING -p tcp --syn -j DROP

Unfortunately, it seems like 10000 is the highest limit and
limit-burst can go. I could duplicate that rule multiple times to get
higher, but that would create a massive file for the limits I want,
and would likely create a much greater slowdown than what could be
achieved with a more flexible module.

Does anyone have thoughts on a way to get some sort of rate-limiting
(TBF or otherwise) that can handle more PPS than the limit module
while still being as efficient as possible?
