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>
