+--no-latency-control
+:   sacrifice latency to improve bandwidth benchmarks. ssh
+    uses really big socket buffers, which can overload the
+    connection if you start doing large file transfers,
+    thus making all your other sessions inside the same
+    tunnel go slowly. Normally, sshuttle tries to avoid
+    this problem using a "fullness check" that allows only
+    a certain amount of outstanding data to be buffered at
+    a time.  But on high-bandwidth links, this can leave a
+    lot of your bandwidth underutilized.  It also makes
+    sshuttle seem slow in bandwidth benchmarks (benchmarks
+    rarely test ping latency, which is what sshuttle is
+    trying to control).  This option disables the latency
+    control feature, maximizing bandwidth usage.  Use at
+    your own risk.
