1。它會根據網站的內容給出建議 (如何更快)

2。分高、中、低，何項該優先處理比較好

3。它會給評份，總分100，分數愈高當然指的是網站load的愈快

全虛擬化--full virtualization

代表作 : virtualbox 跟 kvm

有測試過，並發現的缺點:

1。子機會彼此影響 : 當某子機負載高時，其它子機會明顯的變慢

2。母機關機，子機無法自動關機

半虛擬化--para virtualization

代表作 : xen

我測試過 xen server 3

以上兩個缺點，xen server 3 我是沒遇過，
 
不過有可能是測試環境皆不同、測試的時空背景不同，有可能是硬碟IO的關系吧

ispCP是從 VHCS 延伸而來的

Quote: http://isp-control.net/project-info.html

What is isp Control Panel?

isp Control Panel (ispCP) is an open source project founded to build a Multi Server Control and Administration Panel. This Control Panel is usable by any Internet Service Provider (ISP).

Rather than start a project from scratch, the team searched for existing open source implementations and decided to fork the dying Virtual Hosting Control Panel (VHCS) project. This community effort to continue on the work of VHCS lead to the creation of ispCP Omega.
ispCP Omega release

The ispCP Omega release is completely based on the original open source VHCS project. Because part of the ispCP dev team were core members of the dead VHCS project, Malte (ephigenie) and Benedikt (RatS) felt an obligation to offer the desperate community a way to migrate to ispCP. This led to the creation of ispCP Omega, a migration path from VHCS to ispCP, allowing the community to enjoy a fast, reliable and stable platform with unlimited growth potential.
