<li>
<p>In the navigation tree, expand the Configuration node.</p>
</li>
<li>
<p>Under the Configuration node, expand the Network Config node.</p>
</li>
<li>
<p>Under the Network Config node, select the Transports node.</p>
<p>The Transports page opens.</p>
</li>
<li>
<p>On the Transports page, click the name of the transport that you are editing.</p>
<p>The Edit Transport page opens.</p>
</li>
<li>
<p>In the Classname field, type the class name of the transport implementation.</p>
<p>The default value is <code>com.sun.grizzly.TCPSelectorHandler</code>.</p>
</li>
<li>
<p>In the Selection Key Handler field, type the class name of the selection key handler.</p>
<p>The class name of the selection key handler. A selection key handler is an abstract class that manages the lifecycle of selection keys. If you do not specify a value, a default implementation is used.</p>
</li>
<li>
<p>From the Byte Buffer Type drop-down list, select the type of <code>ByteBuffer</code> to be used.</p>
<p>Available choices are <code>HEAP</code> and <code>DIRECT</code>. The default value is <code>HEAP</code>.</p>
</li>
<li>
<p>In the Acceptor Threads field, type the number of processors in the machine.</p>
<p>A value of -1 indicates that Grizzly will calculate the number of acceptor threads itself, based on the number of processors in the machine. The default value is 1.</p>
<p>To set the number of request processing threads, set the Max Thread Pool Size value of the thread pool used by a network listener that uses this transport.</p>
</li>
<li>
<p>In the Max Connections Count field, type the maximum number of pending connections on a network listener that uses this transport.</p>
<p>The default value is 4096.</p>
</li>
<li>
<p>In the Buffer Size field, type the size, in bytes, of the buffer to be provided for input streams created by a network listener that uses this transport.</p>
<p>The default value is 8192.</p>
</li>
<li>
<p>In the Idle Key Timeout field, type the number of seconds after which an idle key will be cancelled and the channel closed.</p>
<p>The default value is 30.</p>
</li>
<li>
<p>In the Read Timeout field, type the number of milliseconds the GlassFish Serverwaits during the header and body parsing phase of a read operation.</p>
<p>The default value is 30,000.</p>
</li>
<li>
<p>In the Selector Poll Timeout field, type the number of milliseconds a NIO Selector will block waiting for events (users' requests).</p>
<p>The default value is 1000.</p>
</li>
<li>
<p>In the Write Timeout field, type the number of milliseconds the GlassFish Serverwaits before considering the remote client disconnected when writing the response.</p>
<p>The default value is 30,000.</p>
</li>
<li>
<p>Select the Display Configuration Enabled checkbox to flush Grizzly's internal configuration to the server logs.</p>
<p>This option may provide useful information for debugging. This option is disabled by default.</p>
</li>
<li>
<p>Select the Snoop Enabled checkbox to dump the requests/response information to the server log.</p>
<p>This option may provide useful information for debugging, but will significantly reduce performance. This option is disabled by default.</p>
</li>
<li>
<p>Select the TCP No Delay checkbox to enable TCP_NODELAY (also calledNagle's algorithm).</p>
<p>This option is enabled by default.</p>
</li>
<li>
<p>Click Save.</p>
