Tutorials: How to identify a VPS is Good or Bad?

Spance

Hello,

Today I will tell us how to identify a VPS is Good or Bad from cpuinfo,

This is a comparative schematic.

Many modern programs need many advanced CPU features to accelerate running (such as openssl,openssh...), if the CPU looks like the left side(QEMU CPU missing many CPU features) then many modern programs will run very slowly.

• Left side: from an amateur VPS provider.
• Right side: from a professional VPS provider.

A simple proof, test aes: openssl speed -evp aes-128-cbc

• Left side:

......
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
aes-128-cbc      90236.02k   101518.57k   105166.85k   227777.33k   229786.97k

• Right side:

......
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
aes-128-cbc     347680.46k   437552.70k   454087.68k   459527.85k   459576.66k

Actually, the left side has better hardware than right side, but there is a poor result on left side due to insufficiently professional attitude.

It's very important how many CPU features could be exposed to the guest machine. AWS, gcloud, digitalocean and even some small providers.... they have exposed all cpu features to the guest.

Ok

lol.

Lol.

time to summon ftn, postcd, ymmer and friend

nice tutorial, keep up the good work :P

robohost

Nah that's not showing good vps all hail dd god

How to identify a bad VPS provider?

If it costs less per month than a cup of 3rd world gas station coffee then they probably aren't someone you'd want to do business with

geekbench will also give an indication if they are any good, see how much they are overselling the cpu

Can you plz add a few more important commands / tests for :

• Disk Check / Read Write
• Latency Check
• IO

Some providers are willing to unmask the CPU to solve this issue.

Although I think its stupid that you even have to ask about it. I feel its a sign of an inexperienced host.

cpuinfo coming from a MyCustomHosting @MCHPhil VPS. So by interpreting this by your results this is amateur and bad VPS ? That's funny

well its not passing AES-NI

You are very very right, your QEMU Virtual CPU is the super best CPU in the world.

I'm a complete hobbyist that barely understands the difference between either of the configurations here. Apparently I'm a good provider according to this post. +1

Even the CPU on vultr VPS show up as a virtual one. This guide is wrong.

But to his defense a vultr vps should have a lot of cpu flags showing up in contrast to "left provider".

@op simply put you are an idiot. Many if not all modern programs work on qemu. You do however lose functionality to accelerate certain tasks, but by no means does it make it unfuctional.

The reason to use qemu is to allow for better migration between servers, as well as liv migrations.

okay, next tutorial.

LOL...in the SolusVM CP, there is an option which CPU model to show to the VPSes. If he 'Show Host Model' is checked, then only it will show the original CPU model. Else it will show only QEMU vCPU. But that does not necessarily mean that the VPS is BAD. There are a number of other factors that determine whether a VPS is bad or not. Like Disk I/O, network speed, etc.

thank you OP for the courage to post, even this true or false, ppl should reply in manor. IMHO.
