This all depends on what your filters do.
If each filter is creating wrappers, analysing output stream and so on,
you could indeed get performances issues.
Consider each filter is about 3~4 additional stack level.
Also each filter = 1 object + it's configuration datas

If your filter really wants to do a RequestDispatcher.foward() call
(to go someplace other than the servlet that the original request URI
is mapped to), you can do that too ... you're not stuck with
redirects. That way you don't lose your request parameters and

Frank's suggestion might work, although note that it would result in
the discarding of all request parameters, which may not be what you
want.
If you have complex session initialization logic in an Action and you
want to use it in the Filter, I'd suggest factoring it out into a
utility class.
response.sendRedirect(url);
That's what I do. You do get a reference to request, so I would assume
you could get a dispatcher off it and do what you always do. I've never
had a need to try it though.

I always use filters when programming. Unfiltered cigarettes are twice
as likely to give you cancer. ;)
