VPS vs Dedicated Server Performance in real time - Page 2

High end VPS can be more powerfull than a low ends dedicated servers, just to be sure your host don't oversell the VPS ressource, try to find quality before cheapest price.

A dedicated server will outperform a VPS with the same specs (same memory, same CPU's, same disks). It may only outperform by 3% depending on the technology (Virtuozzo is fastest, Xen a bit slower on diskIO), but dedicated is *always* faster on the same hardware.

A dedicated server will also cost about 2-4 times as much.

So take your pick. Do you need that 3%?

After you make that choice, then you can start shopping around.

Much of the comparison is going to depend on the specs of the hardware, what type of processes are being run, and at the end of the day, how much money is being spent.

If you need a shell environment with root access to compile apache or additional software and don't need much power, then a VPS is ideal. Usually with VPS systems you are sharing the system with 8-20 other people. So you only get a portion of the system resources. You usually get a small arount of memory (which can BURST to larger amounts if nobody else is using the memory at the time).

On a dedicated server, you get FULL access to everything. Again, depending on the money spent you can get a dedicated server that is actually weaker than a VPS. Don't buy an Old 1.2Ghz Celeron with 512MB RAM unless that's all you need. The $50-80 is hardly worth it.

For about $200 you can pick up a quadcore xeon with 2GB of ram and large disk space, but again, do you need that much power? If not, then a VPS might be the route to go.

VPS and Dedicated are two very different environments due to how the process and specs are setup. It would be no different than comparing Shared Hosting with VPS in many instances.

That is a very good comparison. I always go for dedicated servers because it gives me a lot of freedom. Freedom in whatever I do. You are also right about choosing a dedicated server. We have to buy a server which is based on our requirements.

From my experience, if the dedicated resources are the same than VPS may perform better. Let me explain.

You CAN have resources dedicated with a VPS just as with a Dedicated server. With a VPS(depending on the setup) many identical processes can be shared between VPS.. Then you have the possibility of burst, and drives that are already raided(if your vps provider doesn't raid then you're in trouble!).

But as others have mentioned, it's simply best to choose what's best for whatever you're using it for. Although my business promotes the use of VPS, there's obviously many times when dedicated is best.

The only way that someone from another VPS Accounton the same machince could hack/deface your VPS Account would be if they gained ROOT access to the server at which point EVERYONE is vulnerable.

That is true for the most part. However, if another VPS on the host server is compromised and launches a DoS attack that uses the NIC in it's entirety, that would most definitely have a negative impact on your VPS. We've had it happen once or twice and it wreaks havoc until the IDS can kick in and let us know what's going on. In addition, if the VPS Host Server itself is compromised, there's a good chance you can say goodbye to all the VM accounts. Now that would suck.

It really depends on what your needs are and who your providers are. However the difference between vps and dedicated is that with dedicated you are the only person with files on the server while VPS is a virtualization environment where everyone gets root access inside a virtual machine, but there are multiple people with these VMs on one given physical server.
If you are comfortable managing your sites in a VPS as root, then it won't be any more difficult to manage them on a dedicated server.

Very well said

In my opinion, dedicated servers are the better option. They are better in terms of memory usage and bandwidth.

Take the scenario Conor dicsussed referencing memory - a VPS with 2GB of dedicated memory that can burst versus a dedicated server with 2GB of memory that can't burst - which is better in terms of memory usage? Where do you set the baseline for comparison?

Dedicated server is for obv. better thn vps...

This is very true. We use a VPS and sometimes our sites/applications really slow down. Remember if your host has one big 16GB dual CPU Server with say 4 disks in a RAID conf BUT has 16 VPS environments all possibly running multiple sites in those environments then there us a lot of disk activity. Those disks can only read and write certain amounts of data no matter what.

We are suffering slow speed on our sites from heavy bandwidth and disk activity from other VPS users. One of our VPS is idle much of the time and runs pretty fast, but sometimes we suffer slow speeds in those idles times because of the hardware activity. VPS environments are great, but they cannot allocate you dedicated resources on the NIC and disks (OpenVZ for certain) so you will suffer performance issues if others on the node are hogging!

In my opinion and testing, dedicated servers are much better and perform better consequently in line with our apps. VPS are cheap, quick and easy to setup.

With a dedicated server it means just that its all yours. Although VPS you get all your own software and environment and you share hardware. Anything that you share means slower.

This all depends on that is virtualizing the servers and what hardware is used. If you are using fiberchannel SAN's and big servers you can have a VPS running like a dedicated server performance wise.

It is all about resource, you can't compare a 4GB VPS with 4 cores shared with a dedi server with 2GB RAM and duo core cpu.

katyperrykissed · Post #29 (**permalink**) 04-30-2010, 04:33 PM

Surely everyone would think costly dedicated servers will perform better than VPS BUT...

I experimented with both on MyHosting and from my experience, high end VPS packages were better than the low cost dedicated servers.

Just from my observations of course. They also answered my questions regarding pricing and VPS pricing was really attractive.

fanturo · Post #30 (**permalink**) 05-11-2010, 07:27 AM

it solely depends on the specs and the load on the server. I know vpses that are faster than dedicated servers.
