对于 Pacificrack 小内存VPS与Vultr VPS 的横向测评

发布于 2020-01-18  255 次阅读


多年没有折腾过服务器了,直到最近发现曾经在 DigitalOcean 做推广获得的75美元赠金竟然过期了?!再加上自己一直都有重新把博客建起来的想法,便打算入手一台VPS把博客搭起来。因为本人是一位穷逼学生党,自然就只能选择便宜的年付小内存 VPS 。恰逢 pacificrack 这家服务商在搞活动,几美元就可以买一年,赶紧上车。

一、购入

pacificrack 是一家最近才火起来的服务商,据说是国人运营的 quadranet 的子公司(pacificrack 好像就是 quadranet 的曾用名)。机房在 quadranet 自家的机房里,目前走的是 CN2 GT 线路,如果不翻车的话性价比那是非常高了。但是这家的口碑比较两极分化,有的人用起来觉得很不错,有的人却连环翻车,初步估计是分到的母鸡不同的锅,真一切全看脸😂。

购买支持使用支付宝付款,博主购买的是7.25美元一年384MB内存的元旦优惠 VPS ,分分钟付款开机。

二、与 Vultr 的对比测试

由于 Pacificrack 在面板里最高只有 Debian 9 64位版本可选,所有测试都运行在 Debian 9 环境下。同时,为了控制变量,测试用 Vultr VPS 的位置为美西洛杉矶机房,配置为1H1G。

1、服务器性能

IO测试

第一次:
I/O speed(1st run)   : 89.4 MB/s
I/O speed(2nd run)   : 104 MB/s
I/O speed(3rd run)   : 92.0 MB/s
Average I/O speed    : 95.1 MB/s
第二次:
I/O speed(1st run)   : 90.1 MB/s
I/O speed(2nd run)   : 88.0 MB/s
I/O speed(3rd run)   : 95.4 MB/s
Average I/O speed    : 91.2 MB/s
第三次:
I/O speed(1st run)   : 111 MB/s
I/O speed(2nd run)   : 112 MB/s
I/O speed(3rd run)   : 131 MB/s
Average I/O speed    : 118.0 MB/s
Vultr
I/O Speed( 1.0GB )   : 356 MB/s
I/O Speed( 1.0GB )   : 353 MB/s
I/O Speed( 1.0GB )   : 346 MB/s
Average I/O Speed    : 351.7 MB/s

I/O speed(1st run)   : 341 MB/s
I/O speed(2nd run)   : 351 MB/s
I/O speed(3rd run)   : 350 MB/s
Average I/O speed    : 347.3 MB/s

和 Vultr 相比这样的IO成绩肯定不算快(毕竟人家用的可是 SSD ,但用来建站也差不多够了。

令人出乎意料的是,pacificrack 的性能竟然好于 Vultr。这对于一些比较吃 CPU 的应用可能会有些帮助。

显然,pacificrack 的网速实在是过于缓慢,无论是在国内还是国外,都被 Vultr 甩了几条街。尤其是对于移动和电信的用户,更是惨不忍睹。(当时买的时候说是 CN2 VPS,现在看来是一条假 CN2 了。)

还想得知更详细信息的朋友可以访问: pacificrack Vultr,里面有了各种各样的测试结果,包括网速、路由、Ping 等。

三、总结

总的来说,pacificrack 的 VPS 虽然卖的便宜,但各项性能都不太好,特别是具有网络连接缓慢这个致命伤。打算用它来建站的朋友可得小心了,不过联通用户拿来停飞机倒是一个不错的选择。

各位想要建站的朋友可以考虑 Vultr 。新用户用我的 aff 可以获得$100的体验金噢。链接:https://www.vultr.com/?ref=8379290-6G
