+ <div class="warning">The buffer filters read the request/response into
+ RAM and then repack the request/response into the fewest memory
+ buckets possible, at the cost of CPU time. When the request/response
+ is already efficiently packed, buffering the request/response could
+ cause the request/response to be slower than not using a buffer at
+ all. These filters should be used with care, and only where
+ necessary.</div>
