tc filter scalability

Has anyone tested the scalability of using tc filters? I have a box which I require to traffic shape each individual client by IP Address using u32 identifiers. My concern though, is that each client requires 2 filters (data from and to the box) and there are a few hundred clients minimum. Which means each packet may have to pass through a few hundred or possibly thousand filters to determine its path. Is this going to give significant latency issues? Or excessive server load?

Is there a simpler way to restrict each client to a given rate (there are three separate rates that different clients are assigned)?

Kind regards,
