+<h4>Memory requirements</h4>
+
+<p>
+Our VM is currently optimized for server class loads. This means that besides
+the usual Java heap settings which are controlled trough command line options
+the user has to make sure the environment provides reasonable data segment and
+the stack size limits. We recommend setting the stack size limit to 4MB
+(e.g. call '<code>ulimit -s 4000</code>') and the data segment limit to 1GB
+(e.g. call '<code>ulimit -d 1000000</code>'). Higher limits should be OK (the
+current limits can be inspected with '<code>ulimit -a</code>').
