Review Quantum Core VPS

Right now, I want to review my VPS on QuantumCore. I had this server because of their offer post on LET. Activated on Friday, March 18th, 2022 only $1AUD for The First 3 Months of 1GB VPS.

Introduction

QuantumCore is 100% Australian owned and operated. The team behind them have over 20 years of experience in the Web Hosting industry. Their nodes have a 1Gb link, clock speeds of 2.70GHz+ and use pure NVMe storage and located Equinix Data Centres in Sydney.
Ping/tracert IP is: 103.246.250.3
Looking Glass: https://lg.quantumcore.com.au/

I test their QUBIT-1 plan, which have specifications :

 30GB Pure NVMe Storage
 1 vCPU - Xeon Gold Processor 2.7GHz
 1GB Memory
 1TB Bandwidth
 1 IPv4 Address
 1 IPv6 Address (On Request)
QUBIT-1 of QuantumCore specifications

VPS Panel

They are using SolusVM as their VPS management system, you can manage your server on their Client Area. Their SolusVM panel include :

  • Server Information (your server specifications like Online status, Main IP Address, Monthly Bandwidth, Memory and HDD)
  • Boot / Reboot / Shutdown
  • Console / NoVNC Console
  • Reinstall OS (Rebuild x86_64 OS) -> Almalinux8, CentOS 6, CentOS 7, CentOS 8, Debian 9, Debian 10, Ubuntu 16.04, Ubuntu 18.04, and Ubuntu 20.04
  • Graphs (to check your network traffic usage) screenshot
  • Reverse DNS (Some hosting company disable this feature or maybe charge it, but QuantumCore enable it for free) screenshot 🤤
  • You can't direct login to their SolusVM panel to manage your server, but don't worry all basic vps panel management stuff is available on their clientarea (whmcs).
  • No ISO installation method 😪

Uptime

For the record, i wrote this post on May 17, 2022. So the server should been online since 59 days ago, and when i access today, my uptime command output :

root@ubuntu20:~# uptime
 15:24:30 up 59 days, 21:08,  1 user,  load average: 0.00, 0.00, 0.00

Benchmark

Benchmark yabs

Benchmark this server with yabs.sh to check server specifications, test CPU, storage, and network. This benchmark result was done after fresh OS installation to get best result.

root@ubuntu20:~# curl -sL yabs.sh | bash

Network

To check network of this vps i used online tool ping.pe, if you're on asia pasific region, you may focus ping on Singapore, Japan, India and Australia.

Average ping on Singapore ping : 93.41 ms, Japan 217.9 ms, Mumbai (West India) 277.89 ms and Bengaluru (Central India) 152 ms and Australia 1.25 ms

Load Test

To check load test server responses, i installed EasyEngine for easy wordpress with nginx installation and Loader.io to test the wordpress site, 1000 client in 1 minute.

ee successfully setup.

EasyEngine successfully installed

Easyengine default installation used PHP8 and MariaDB 10.5 based on easyengine/mariadb:v4.1.3 docker image. Now i want to load test with loader.io with configuration : 100 clients over 1 min and 1000 clients over 1 min.

Load test 100 clients over 1 min

Average responses time is 8462 ms (10 second) with 50.4% error rate.

Load test 1000 clients over 1 min

Load test results on Quantum VPS Qubit-1 plan

Average responses time is 10070 ms (around 10 second) with 95% error rate.

Bonus (Capable to install windows or not?)

Last but not least, if you have read my post before (Quick Install Windows Server with Windows template), this vps use vda disk with 30GB diskspace. So i decided to install windows 2012 R2 to this server using Rescue, and voila !

Windows 2012 R2 Successfully installed on QUBIT-1 plan QuantumCore

Windows 2012 R2 Successfully installed on this server, with around 500MB Available RAM and not so excessive CPU usage.

Conclusion

Quantumcore VPS Qubit-1 plan ($5 AUD per month) with specifications : 1 Core Xeon Gold (single core value : 741), 1GB RAM, 30GB NVME.

This server can still achieve 50 clients over 1 min when loadtest with loader.io with around 5000ms (5sec) and 0% error rate which is all of 50 users still can access the site but with 5 sec responses time.

Quantumcore Qubit-1 plan network speeds is quite good based on yabs benchmark, but in my opinion this vps have best optimal results if you lived around southeast asia like Singapore, Indonesia, Malaysia and local Australia.
