平时在线人数：5000~10000人 峰值：50000+（超过5w后，统计表性能明显下降，关闭了统计）

之前每逢峰值论坛常挂，改造之后有充足的预案防止出问题，保证论坛用户能及时在论坛传达必要消息。

在论坛改造过程中，我写了很多文章来表述改造中的一些心得，也认识了很多朋友一起讨论dz的优化。其中最宝贵的经验，是一些无能为力的站长把他们的服务器交给我，让我亲手在一个大负载的服务器上去做优化，在这个过程中学到了很多系统优化方面的知识，更宝贵的是获得了大负载下dz的一些瓶颈点的数据。

由于考虑用户群的问题，很多技术没有办法用开源的软件实现，也无法找到替代品，考虑实际，很多dz站长自己并没有实力去涉入维护一个更改很多的论坛，所以我的方案并没有大量去应用。

在帮朋友优化的过程中，提到更多的是技术实力与维护、需求的增删与性能的平衡。

所以，我得出这样的结论供大家参考：

1、每个功能都会吃系统资源，充分考虑每个功能是否必须，不必须的功能一定要砍。

2、找系统压力点：根据我对逍遥论坛用户日志的分析，90%的压力集中在 forumdisplay.php viewthread.php上，而这些脚本的压力主要体现在表联查而造成的锁表上，最主要的表就是sessions表。sessions表集合了很多用户统计相关功能，因为，优化此表，结合上条原则，合理增删功能，达到压力减小。

3、硬件的优化。硬件优化也是我最近考虑的一个方案，想对于开发人员，硬件的开销还是很小的。合理升级硬件也是一个不错的方案。

以上结论是针对中小型网站已经碰到瓶颈的dz程序做出的建议。

而对于一个负载很大，并且有实力的团队，那在discuz上要做的文章就太多了。

1、拆表是必然的，而对于一些数据量不大但经常变动的表，完全可以全cache。

2、根据需求删改功能。discuz很强大， 但不是每个功能都是你必须使用的。

3、开源产品会给你很多灵感。

推荐的一些开源技术方案：

memcached(不用说了)

Tokyo Cabinet DBM:性能极佳的持久存储的keyvalue数据库

mysql udf http http://blog.s135.com/mysql-udf-http/ 让tt变成从库？

lucene 必须要替换discuz默认的搜索

你还有什么想法？

一时兴起，写此文。欢迎有兴趣的朋友加 discuz性能优化讨论群 qq:41886598

后发现有些机器的版本可以，有些不可以，详细比较后，发现原来是中国版的才有这个功能。

后安装中国版后此功能再现。

我一直认为这个功能很不错，遨游这类浏览器基本也是标配功能，而国际版的为什么就没有？

vsuch网站使用lamp＋windows混合平台（汗），追究历史，原来网站用.net编写，后用php重构了整个网站。

整改前 Mysql运行在linux机器上，php运行在windows平台上，中间局域网方式连接。

网站日访问量不小，alexa排名6800，windows平台明显抗不住，经常莫名其妙的问题。（题外话：我最早维护的服务器也是windows，apache在上边很不稳定）

了解后，我感觉一台服务器就足矣，放弃了apache的方案，安装了nginx＋php，数据库依然沿用原来的。

整改后，linux负载稍稍升高，mysql负载不变，http的负载在nginx下并没有表现出多高。顺利完成了迁移。

后公司又开通了cdn服务（有钱），速度有了很明显的提升。

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

根据其公司目前的技术结构，我提出了很多优化和整改的想法，希望每个创业网站都能走好。

  • If a method can be static, declare it static. Speed improvement is by a factor of 4.
  • echo is faster than print.
  • Use echo’s multiple parameters instead of string concatenation.
  • Set the maxvalue for your for-loops before and not in the loop.
  • Unset your variables to free memory, especially large arrays.
  • Avoid magic like __get, __set, __autoload
  • require_once() is expensive
  • Use full paths in includes and requires, less time spent on resolving the OS paths.
  • If you need to find out the time when the script started executing, $_SERVER[’REQUEST_TIME’] is preferred to time()
  • See if you can use strncasecmp, strpbrk and stripos instead of regex
  • str_replace is faster than preg_replace, but strtr is faster than str_replace by a factor of 4
  • If the function, such as string replacement function, accepts both arrays and single characters as arguments, and if your argument list is not too long, consider writing a few redundant replacement statements, passing one character at a time, instead of one line of code that accepts arrays as search and replace arguments.
  • It’s better to use switch statements than multi if, else if, statements.
  • Error suppression with @ is very slow.
  • Turn on apache’s mod_deflate
  • Close your database connections when you’re done with them
  • $row[’id’] is 7 times faster than $row[id]
  • Error messages are expensive
  • Do not use functions inside of for loop, such as for ($x=0; $x < count($array); $x) The count() function gets called each time.
  • Incrementing a local variable in a method is the fastest. Nearly the same as calling a local variable in a function.
  • Incrementing a global variable is 2 times slow than a local var.
  • Incrementing an object property (eg. $this->prop++) is 3 times slower than a local variable.
  • Incrementing an undefined local variable is 9-10 times slower than a pre-initialized one.
  • Just declaring a global variable without using it in a function also slows things down (by about the same amount as incrementing a local var). PHP probably does a check to see if the global exists.
  • Method invocation appears to be independent of the number of methods defined in the class because I added 10 more methods to the test class (before and after the test method) with no change in performance.
  • Methods in derived classes run faster than ones defined in the base class.
  • A function call with one parameter and an empty function body takes about the same time as doing 7-8 $localvar++ operations. A similar method call is of course about 15 $localvar++ operations.
  • Surrounding your string by ‘ instead of ” will make things interpret a little faster since php looks for variables inside “…” but not inside ‘…’. Of course you can only do this when you don’t need to have variables in the string.
  • When echoing strings it’s faster to separate them by comma instead of dot. Note: This only works with echo, which is a function that can take several strings as arguments.
  • A PHP script will be served at least 2-10 times slower than a static HTML page by Apache. Try to use more static HTML pages and fewer scripts.
  • Your PHP scripts are recompiled every time unless the scripts are cached. Install a PHP caching product to typically increase performance by 25-100% by removing compile times.
  • Cache as much as possible. Use memcached - memcached is a high-performance memory object caching system intended to speed up dynamic web applications by alleviating database load. OP code caches are useful so that your script does not have to be compiled on every request
  • When working with strings and you need to check that the string is either of a certain length you’d understandably would want to use the strlen() function. This function is pretty quick since it’s operation does not perform any calculation but merely return the already known length of a string available in the zval structure (internal C struct used to store variables in PHP). However because strlen() is a function it is still somewhat slow because the function call requires several operations such as lowercase & hashtable lookup followed by the execution of said function. In some instance you can improve the speed of your code by using an isset() trick.Ex.if (strlen($foo) < 5) { echo “Foo is too short”; }

    vs.

    if (!isset($foo{5})) { echo “Foo is too short”; }

    Calling isset() happens to be faster then strlen() because unlike strlen(), isset() is a language construct and not a function meaning that it’s execution does not require function lookups and lowercase. This means you have virtually no overhead on top of the actual code that determines the string’s length.

  • When incrementing or decrementing the value of the variable $i++ happens to be a tad slower then ++$i. This is something PHP specific and does not apply to other languages, so don’t go modifying your C or Java code thinking it’ll suddenly become faster, it won’t. ++$i happens to be faster in PHP because instead of 4 opcodes used for $i++ you only need 3. Post incrementation actually causes in the creation of a temporary var that is then incremented. While pre-incrementation increases the original value directly. This is one of the optimization that opcode optimized like Zend’s PHP optimizer. It is a still a good idea to keep in mind since not all opcode optimizers perform this optimization and there are plenty of ISPs and servers running without an opcode optimizer.
  • Not everything has to be OOP, often it is too much overhead, each method and object call consumes a lot of memory.
  • Do not implement every data structure as a class, arrays are useful, too
  • Don’t split methods too much, think, which code you will really re-use
  • You can always split the code of a method later, when needed
  • Make use of the countless predefined functions
  • If you have very time consuming functions in your code, consider writing them as C extensions
  • Profile your code. A profiler shows you, which parts of your code consumes how many time. The Xdebug debugger already contains a profiler. Profiling shows you the bottlenecks in overview
  • mod_gzip which is available as an Apache module compresses your data on the fly and can reduce the data to transfer up to 80%

    但一般的中小网站依然提倡免费开源的解决方案，造成我思想上一些束缚， 没有去发散性的组织一些解决方案。这块原来是我发展的失误。曾经一个些java的大哥提醒我，不要过分迷信开源。事实的确是这样。以后逐渐接触好的商用软件，望有条件的朋友给予支持。

    相比apache，功能没有显少，但效率和负载却很强。Zeus支持FastCGI的方式来运行PHP，这样LZMP的架构的确也很强。

    Web Service主要是为了使原来各孤立的站点之间的信息能够相互通信、共享而提出的一种接口。 Web Service所使用的是Internet上统一、开放的标准，如HTTP、XML、SOAP（简单对象访问协议）、WSDL等，所以Web Service可以在任何支持这些标准的环境（Windows,Linux）中使用。注：SOAP协议（Simple Object Access Protocal,简单对象访问协议）,它是一个用于分散和分布式环境下网络信息交换的基于XML的通讯协议。在此协议下，软件组件或应用程序能够通过标准的HTTP协议进行通讯。它的设计目标就是简单性和扩展性，这有助于大量异构程序和平台之间的互操作性，从而使存在的应用程序能够被广泛的用户访问。

    最近写一个认证服务器，需要进行不同程序，不同数据库之间的数据交换，认证服务器提供认证功能，而客户端可能是多种语言开发的。如果实用传统的方式，比如C，或者java开发一个稳定的服务端，人力精力都是问题，只能寻求一种简单的方式进行过渡。

    这里我选择了Web Service这种方式，但这种方式也存在一定问题：速度。网上普遍反映速度是问题，soap的方式本身负载是问题，实用xmlrpc，http方式，瓶颈在于webserver的负载能力。但是项目发展初期，此方式完全能满足一段时间，而这段时间我们也能平滑过渡，留出时间进行更深层次的研究。

    一个是adodb的完整版本，一个是adodb lite版本。其实我一直在比较这两个版本的具体区别，和效率问题。另外主要考虑了它的扩展性和兼容性。

    经过比较，我选择了lite版本，因为速度，adodb的功能是比lite完善不少，但过于庞大，真正想象，我根本不用那些功能。比如oracle数据库，没人会在oracle上用我这么点个程序。

    不过两个类库的方法命令语法基本都一致，我可以轻松切换了。

    稳定的系统，就得这样一点点得锤炼才行。

    　20世纪40年代中期，人类发明了有史以来最具破坏性的武器。原子弹让人们夜不成眠，但真正造成巨大破坏的却是AK-47。这种有显眼黄色弹匣的冲锋枪造成的死亡和毁灭多过任何其他现代化武器。到今年它已经问世60年了，但还没有一点退休的迹象。

     

    它的发明者、俄罗斯的卡拉什尼科夫现在已经近90岁了，住在莫斯科以东1130公里处乌拉尔地区的伊热夫斯克市。他对自己的这项发明内心很矛盾。他仍为向苏联普通士兵提供了这样一种强大的武器而感到自豪，但又因为自己的名字跟死亡和恐怖联系在一起而感到懊悔。“一旦有人发明出一种更好的冲锋枪，我就会跟他握手。但目前这件事情还没有发生。”

     

    牛津大学教授菲利普·基利科特（Phillip Killicoat）在提交给世界银行的论文《武器经济学:冲锋枪的全球市场》中分析了AK-47为什么在世界各地有不同的售价。比如AK-47在非洲通常要比在其他地方便宜200多美元。基利科特说:“非洲各国的边境管理比其他地方要宽松很多，冲锋枪在非洲的交易不太受管制，当需要购买这种武器时几乎不存在贸易壁垒。一个时期非洲只有几个国家因为发生冲突而需要武器，宽松的边境管理使得非洲的武器供应可以满足这些国家的需要。”

     

    基利科特还解释了为什么世界各地的交战双方都选用这种武器。通常做法是像迈克·霍奇一样，把这归因于AK-47功能上的特点:容易操作，造价低廉，坚实耐用，故障率低。而它不够精准、对使用者来说不够安全、瞄准范围相对较小的缺点都被忽略掉了。这种解释有一个说不通的地方，即其他操作同样简便的冲锋枪就没有像卡拉什尼科夫设计的这种枪这样被广泛采用。

     

    　　基利科特提出，AK-47的流行可以用路径依赖理论（path dependence）来解释。1936年，美国发明家德沃夏克（Dvorak）博士历经十余年的研究发明了ASK键盘（American　 Simplified　Keyboard，即美式简化键盘），他声称这种键盘比打字机发明者、美国人肖尔斯1870年设计的、现在通用的QWERTY键盘效率更高。据说当初肖尔斯在研制打字机时，为了解决打字员打字速度过快造成挤塞的问题，故意打乱了字母排列顺序，形成了直到今天通用的QWERTY顺序排列。不过，德沃夏克先进的ASK键盘没能占领市场，反而逐渐地销声匿迹了，QWERTY一直独霸着键盘市场。

     

    　　美国斯坦福大学经济学教授保罗·戴维认为，QWERTY键盘之所以能在市场上占统治地位，不是因为它的效率高，而是因为它出现得早，普及之后，对它进行更新换代的成本太高。像这样，一个有缺陷的产品由于它早期一个小的优势而被广泛采用之后就独霸了市场的情形被称作“路径依赖”。具体到AK-47来说，它早期的优点或许是它是苏联人的发明，不受知识产权的限制，可以随意仿造。

     

    　　“路径依赖”理论启发商人们想出了一个经营策略:虽然软件公司都抱怨盗版，但他们早就意识到让别人违法地仿造其产品并不是坏事。人人都上钩之后，就可以开始卖升级产品，或者提供服务，附加别的花哨的东西。这是开放源代码的好处。照此说来，苏联的AK-47是世界上最流行的开放源代码冲锋枪。

    http://cn.php.net/manual/en/features.commandline.php

    To ease working in the shell environment, the following constants are defined:

    CLI specific Constants
    Constant Description
    STDIN

    An already opened stream to stdin. This saves opening it with

    <?php

    $stdin

    = fopen(‘php://stdin’, ‘r’);

    ?>

    If you want to read single line from stdin, you can use

    <?php
    $line     = trim(fgets(STDIN)); // reads one line from STDIN
    fscanf(STDIN, “%d\n”, $number); // reads number from STDIN
    ?>
    STDOUT

    An already opened stream to stdout. This saves opening it with

    <?php

    $stdout

    = fopen(‘php://stdout’, ‘w’);

    ?>

    STDERR

    An already opened stream to stderr. This saves opening it with

    <?php

    $stderr

    = fopen(‘php://stderr’, ‘w’);

    ?>

    我比较倾向这种方式，这样就跟c＋＋类似了

    1. <?php
    2. $line = trim(fgets(STDIN)); // reads one line from STDIN
    3. fscanf(STDIN, "%d\n", $number); // reads number from STDIN
    4. ?>
