		<description><![CDATA[shell&#62; mysql Client does not support authentication protocol requested by server; consider upgrading MySQL client 官方的说法是 MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. &#8230;.. 如果你升级mysql到4.1以上版本后遇到以上问题,请先确定你的mysql client 是4.1或者更高版本.(WINDOWS下有问题你就直接跳到下面看解决方法了,因为MYSQL 在WINDOWS是client和server一起装上了的) 请使用以下两种方法之一 其一: mysql&#62; SET PASSWORD FOR -&#62; &#8216;some_user&#8217;@'some_host&#8217; = OLD_PASSWORD(&#8216;newpwd&#8217;); 其二: [...]]]></description>

		<description><![CDATA[64位与32位 Linux下MySQL性能比较(转) 原帖 http://www.wordyou.com/archives/56 阅读了http://www.anandtech.com/IT/showdoc.aspx?i=2447&#38;p=5的优秀测试，大致得出以下结论： 1. 同主频Xeon下64位性能反而不如32位，Opteron下64bit性能提高大约30％左右，此测试可能与编译器优化有关。 2. 双核比双cpu单核比较性能大约提高6％ 3. 超线程开启性能下降10％左右(MySQL read) 4. InnoDB性能大约是MyISAM的60％，但对于多cpu（核心）扩展性比MyISAM强很多 5. 同主频AMD的Opteron性能比Intel的Xeon高13％左右 6. 不论MyISAM还是InnoDB，4核心(俩双核cpu）比单双核cpu性能仅提高10％ 如果采用xeon服务器，关闭超线程并采用32位系统性能最佳 如果采用opteron，64bit可以获得最佳性能，而单双核cpu就足够理想，四核心对性能提高并不明显。 简单生活。简单运动]]></description>
