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。既然如此还是很自然的选择了它，它的速度让很多客户无法接受，最近忙碌于magento性能优化。
     经过优化后，速度上了几个台阶，觉得能让大部分人都接受了，据本人目测最少快了(7-8倍)。

参考结合了前辈的经验总结了如下很重要的几点:


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 p_w_picpaths
    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
