This + will allow you to configure the size of the TCP connection + lookup hash table. The default is 256 buckets and must be set + to a power of two. This is accomplished with adb against the + *disc* image of the kernel. The variable name is <code>tcp_hash_size</code>. + Notice that it's critically important that you use "<code>W</code>" + to write a 32 bit quantity, not "<code>w</code>" to write a 16 bit + value when patching the disc image because the <code>tcp_hash_size</code> + variable is a 32 bit quantity.</p> + + <p>How to pick the value? Examine the output of <a href="ftp://ftp.cup.hp.com/dist/networking/tools/connhist">ftp://ftp.cup.hp.com/dist/networking/tools/connhist</a> + and see how many total TCP connections exist on the system. You + probably want that number divided by the hash table size to be + reasonably small, say less than 10. Folks can look at HP's + SPECweb96 disclosures for some common settings. These can be + found at <a href="http://www.specbench.org/">http://www.specbench.org/</a>. + If an HP-UX system was performing at 1000 SPECweb96 connections + per second, the <code>TIME_WAIT</code> time of 60 seconds would mean + 60,000 TCP "connections" being tracked.</p> + + <p>Folks can check their listen queue depths with <a href="ftp://ftp.cup.hp.com/dist/networking/misc/listenq">ftp://ftp.cup.hp.com/dist/networking/misc/listenq</a>.</p> + + <p>If folks are running Apache on a PA-8000 based system, they + should consider "chatr'ing" the Apache executable to have a + large page size. This would be "<code>chatr +pi L <BINARY></code>". + The GID of the running executable must have <code>MLOCK</code> privileges. + <code>Setprivgrp(1m)</code> should be consulted for assigning + <code>MLOCK</code>. The change can be validated by running Glance + and examining the memory regions of the server(s) to make sure that + they show a non-trivial fraction of the text segment being locked.</p> + + <p>If folks are running Apache on MP systems, they might + consider writing a small program that uses <code>mpctl()</code> + to bind processes to processors. A simple <code>pid % numcpu</code> + algorithm is probably sufficient. This might even go into the + source code.</p> + + <p>If folks are concerned about the number of <code>FIN_WAIT_2</code> + connections, they can use nettune to shrink the value of + <code>tcp_keepstart</code>. However, they should be careful there - + certainly do not make it less than oh two to four minutes. If + <code>tcp_hash_size</code> has been set well, it is probably OK to + let the <code>FIN_WAIT_2</code>'s take longer to timeout (perhaps + even the default two hours) - they will not on average have a big + impact on performance.</p> + + <p>There are other things that could go into the code base, but + that might be left for another email. Feel free to drop me a + message if you or others are interested.</p> + + <p>sincerely,</p> + + <p>rick jones</p> + + <p><a href="http://www.cup.hp.com/netperf/NetperfPage.html">http://www.cup.hp.com/netperf/NetperfPage.html</a></p> + + </div> +</div> +<div class="bottomlang"> +<p><span>Available Languages: </span><a href="../en/platform/perf-hp.html" title="English"> en </a> | +<a href="../ko/platform/perf-hp.html" hreflang="ko" rel="alternate" title="Korean"> ko </a></p> +</div><div id="footer"> +<p class="apache">Copyright 2009 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p> +<p class="menu"><a href="../mod/">Modules</a> | <a href="../mod/directives.html">Directives</a> | <a href="../faq/">FAQ</a> | <a href="../glossary.html">Glossary</a> | <a href="../sitemap.html">Sitemap</a></p></div> +</body></html>
