+<p>Note that because serf behaves differently to neon,

+performance regressions in some setups.</p>
+<p>The <strong>MaxKeepAliveRequests</strong> option in <code>httpd.conf</code>
+needs to be increased from 100 (the default) to <b>at least</b>1000
+(there is no reason why it could not be 10000).
+This will improve performance by allowing serf clients to use less
+TCP connections to the server.
+Clients using ra_neon will also work fine with this configuration.</p>
+<p>Because serf clients issue a larger number of HTTP GET requests
+than neon clients it is possible that serf clients cause quicker
+growth of httpd server logs than neon clients do.</p>
