magento 性能优化

前言: Magento 是一个开源电子商务系统，尤其以扩展性高著称，但是很高的扩展性往往是牺牲了速度为代价的，虽然现在magento为速度提升做了很多工作，但是还是没能 达到人们对速度的要求。既然如此还是有很多企业选择了它，速度问题还是让很多客户无法接受，最近忙碌于magento性能优化。 同时速度也上了几个台阶，据本人目测最少快了(7-8倍)。 参考了合同前辈的经验总结了如下几点: 1) Magento Caching. Magento 自身cache Goto Magento Admin -> System -> Cache Management - Tick the following items: – Configuration – Layouts – Block HTML output – Translations 2) MySQL Cache Size 设置 query_cache_size=128M innodb_buffer_pool_size=64M innodb_additional_mem_pool=16M 4) Enabling Gzipping 启用gzip压缩 .htaccess php_flag zlib.output_compression on AddHandler application/x-httpd-php5 .css 修改 .htaccess mod_deflate 配置 本人配置如下: # Insert filter on all content SetOutputFilter DEFLATE # Insert filter on selected content types only #AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.06-4.08 have some more problems BrowserMatch ^Mozilla/4\.0[678] no-gzip # MSIE masquerades as Netscape, but it is fine BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # Don't compress images SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary # Make sure proxies don't deliver the wrong content Header append Vary User-Agent env=!dont-vary 5) Install Fooman Speedster 安装该插件 6) Install APC or Xcache 安装apc机器码缓存 <cache> <backend>apc</backend> <prefix>alphanumeric</prefix> </cache> 添加到 app/etc/local.xml <global></global> 之间. 7) 设置apache 开启 KeepAlive KeepAlive ＝ On LoadModule deflate_module     modules/mod_deflate.so #开启mod_deflate 参考地址: http://www.magentocommerce.com/wiki/groups/168/optimising_your_web_stack_performance_for_magento http://www.magentocommerce.com/boards/viewthread/36225/ 出处: 马丁博客［http://www.blags.org/］ 本文链接地址: http://www.blags.org/magento-performance-optimization/
