使用magento運行的清漆設置

Question

我正在使用magento創建電子商務網站。

我正在使用nginx，php5-fpm。

我有512MB RAM和4CPU內核。

我想使用這些規格的清漆。我想知道我應該在清漆配置中設置哪些值，以便我的服務器能夠以最小延遲處理最大請求？我已經嘗試了一些清漆配置，但我得到的響應時間比我沒有清漆的時間長。

這是我一直使用的設置。來自用於magento的Varnish模塊的PageCache。我其實written about setting up this

# This is a basic VCL configuration file for PageCache powered by Varnish for Magento module. 

# default backend definition. Set this to point to your content server. 
backend default { 
    .host = "127.0.0.1"; 
    .port = "8080"; 
} 

# admin backend with longer timeout values. Set this to the same IP & port as your default server. 
backend admin { 
    .host = "127.0.0.1"; 
    .port = "8080"; 
    .first_byte_timeout = 18000s; 
    .between_bytes_timeout = 18000s; 
} 


# add your Magento server IP to allow purges from the backend 
acl purge { 
    "localhost"; 
    "127.0.0.1"; 
}
