近期，UCloud优刻得“全球云产品，全场1折起UCloud全球33个数据中心，29条专线，覆盖五大洲，助力企业出海”海外云主机促销活动页面上香港云主机机型，统一由原先的通用型换成了快杰型，而其他海外可用区依然促销的是通用型云主机。
从UCloud官网控制台也可以看到同等配置快杰型要比通用型便宜一些，那么香港通用型和快杰型云主机性能差别大吗？带着这个疑问，老刘博客测试了促销页面上活动价格首年300元3年800元的1核2G内存2M带宽40G RSSD系统盘香港快杰云主机并与同等配置的香港快杰型云主机作了简单测评对比。下图是两种机型的机器基础信息。
测试工具：站长工具Ping值测试，SuperBench脚本测试和UnixBench脚本跑分。
Ping是潜水艇人员的专用术语，表示回应的声纳脉冲，在网络中Ping是一个十分好用的TCP/IP工具。它主要的功能是用来检测网络的连通情况和分析网络速度。
SuperBench脚本，可以一键测试云主机服务器VPS 各种性能，包括机器基本信息，硬盘读写速度，到国内各个地区的下载速度等。
UnixBench是一个类unix系（Unix，BSD，Linux）统下的性能测试工具，一个开源工具，被广泛用与测试linux系统主机的性能。Unixbench的主要测试项目有：系统调用、读写、进程、图形化测试、2D、3D、管道、运算、C库等系统基准性能提供测试数据，UnixBench运行结束后会给出机器整体性能跑分值，分数越高机器性能越好，一般跑分在1200-1300以上的机器，性能不错，值得入手。
Ping值测试对比
老刘使用站长工具Ping测试分别对通用型和快杰型云主机进行了测试以下是测试结果图：
通用型云主机Ping值
快杰型云主机Ping值
分析：由以上两图可以看出，通用型和快杰型云主机在电信、多线、联通和移动线路上响应时间基本一致，其中通用型平均49.2ms，快杰型平均48ms。

分析：UnixBench测试了系统调用、读写、进程、图形化测试、2D、3D、管道、运算、C库等性能，是一个比较综合性测评机器性能的工具，这里具体各个性能数据不用作分析，这里我们只需要看最后的跑分结果。通用型云主机跑分1514.5，快杰型云主机跑分1714.6，均是在1200-1300分值以上，性能优秀，同时快杰型云主机跑分更高，综合性能较通用型云主机好。
总结，老刘博客通过以上测试结果分析可知，UCloud优科得香港1C2G2M配置的通用型和快杰型在连通性和速度上基本无差别，通用型较快杰型在磁盘读写性能上更好些，而就云主机综合性能考虑，老刘建议选择快杰型云主机，其UnixBench跑分更高。
