I always suppose that a VPS is faster than a shared hosting, is that true or not? but this also is making me confused because a shared hosting package is created from a VPS and it is using the resources of a VPS hence it has same speed with a VPS. Is there a way to compare performance between a VPS and a shared hosting?

Practically VPS hosting will be faster than shared hosting package as VPS server will have its own dedicated resources like ( CPU usage, Dedicated RAM, Bandwidth), while on shared hosting package the resources are shared with other shared hosting accounts. But this need to be test on same conditions for shared and VPS server.

Hi DaRecordon,

A VPS isn't necessarily faster. it depends on how the VPS is configured.

Shared hosting environments have usually been tweaked for performance.

A VPS is a good option if you require more flexibility.

A shared hosting plan isn't always created in a VPS either.

I agree with you a bit more on this but on my VPS I'm also creating accounts to different websites. That can be called as shared hosting accounts?

A shared hosting plan isn't always created in a VPS either.
So, what created shared hosting plan? I am a little confused about this.

The only difference are the resources, which are guaranteed with a VPS, and shared with a shared hosting. But if you host more than 50 websites on a small VPS, it will be very similar to a shared hosting.
The main reason to choose a VPS, is when you have several websites, and you want to be able to manage them all in your own server, or when you have a lot of traffic and need more performances

According to my experience, VPS is better than Shared hosting because it is a private server. Shared hosting is a way for hosting companies to put a large number of users on the same server. A VPS is a private, virtual server that exists on a much more powerful physical machine. It is more reliable and flexible as compare to shared hosting server.

All hosting utilises a physical Dedicated Server in some shape or form.

In Shared hosting, the resources are split between a lot more people than you will find on vps hosting.

For simply sake, imagine this scenario,

Shared hosting - Dedicated server split into 100 chunks for 100 customers
VPS - Dedicated Server Split into 3 chunks for 3 customers
Dedicated Server - You get the entire thing to yourself.

Of course the split isn't exactly this, but it's for the purpose of this simple explanation.

It is because of this you'll find performance benefits due to the fact that the resources are less contended and are guaranteed.
However, It isn't as simple as that as you may already understand. There are other things that contribute to performance such as the speed of the connection, reliability, the hardware the hosting company is utilising, the way it's optimised etc, the list goes on.

Indeed, VPS doesn't mean is faster/more powerful/better than shared hosting. It definitely gives you a lot more control!

The quality of shared hosting depends on the server specs, but also how high the load on the server is (how many websites are running on the server and how much performance the websites need). Shared hosting can be great for normal business with moments of higher traffic. VPS is limited to a certain RAM and cores, which can be result in slower performance on peak times.

Although VPS gives you more control and, it also can give you more option to optimalize your website (caching etc). Of course knowledge of server management will be required.

That is not always the case, most shared hosting plans have a very limited I/O capacity to 1024 KB/s therefore we see this huge gap between a VPS and shared hosting. On the other hand a VPS is not limited to a specific amount its more of a fair share usage concept, therefore a heavly oversold VPS server node might be slower than high-end shared hosting with high allocated I/O resources.

It depends on the type of virtualization technology used for creating the VPS.

If you go for an openVZ it is very possible that you get worse performance than shared hosting but this depends on how oversold the server is.
If you get an KVM powered VPS (which is still possible to oversell) but most KVM plans are dedicated resources.

A VPS is faster because it has dedicated resources which are all directed towards your websites. If another VPS on the same server has programming errors or gets a DDOS attack, then it consumes all the resources of that other VPS, while your VPS stays untouched. A shared hosting has hundreds or thousands of websites on it, and they share the same server resources. If one or several websites are poorly programmed, and have infinite loops, and eat up a lot of resources, or if some websites get DDOS attacks, then all the other websites on that same shared hosting will have less resources available to them, and will start working slow and showing the same slowness signs as the poorly programmed or attacked websites.

Shared Hosting means the host either has a Reseller Account/ VPS or even a Dedicated Server where they have WHM installed on it or Plex or a similar software, usually it's oversold and has high load so that would be the main reason behind it being slow.
VPS is something that's private can't say the resources are Dedicated because overselling could happen on VPS services too.

A VPS is seemed to be faster because it's virtualized whereas Shared Hosting is not virtualized. VPS acts like a Dedicated Server in some cases. There are tons of users in a Shared Hosting server but there is much less users in a VPS Node.
