+<p>Deltas transferred between Subversion 1.10 clients and servers may be
+compressed with LZ4. The actual choice of the compression algorithm depends
+on the used protocol, environment and its configuration &mdash; see below.</p>
+
+<p>For <b>http://</b> protocol, use of LZ4 compression depends on the values
+of the server-side <tt>SVNCompressionLevel</tt> directive, client-side
+<tt>http-compression</tt> configuration option and on the network
+capabilities.  LZ4 compression generally offers much faster compression
+and decompression speeds, but slightly worse compression ratio than zlib.
+By default, it is only preferred for low latency networks where the
+overhead associated with transferring the additional amount of data is
+assumed to be negligible.<p>
+
+<ul>
+  <li>
+    <p>On the <b>server-side</b>, <tt>SVNCompressionLevel 0</tt>
+    can be used to disable compression altogether.  The special value of
+    <tt>SVNCompressionLevel 1</tt> forces the use of LZ4 compression for
+    clients that support it.  All other values result in negotiating the
+    use of zlib compression with the respective compression level, unless
+    the compression is disabled on the client.</p>
+  </li>
+  <li>
+    <p>On the <b>client-side</b>, setting <tt>http-compression</tt> to
+    either <tt>yes</tt> or <tt>no</tt> will disable or enable compression
+    that is then negotiated based on the server's configuration.
+    The default value of <tt>auto</tt> will result in preferring LZ4
+    compression for low latency networks and zlib compression otherwise.</p>
+  </li>
+</ul>
+
+<p>Below is the table explaining the used compression algorithm in each
+combination of the client- and server-side configuration options:</p>
