New Revision: 718086

URL: http://svn.apache.org/viewvc?rev=718086&view=rev

Clarify the documentation for mod_buffer to better explain where the
buffer might be useful, and that buffering is not guaranteed to improve
performance in all cases.

+    <note type="warning">The buffer filters read the request/response into

+        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
