Why VPS is faster than DEDICATED?
 

Here's the server issue:

I'm comparing loading times for two IDENTICAL html sites with no dynamic content. I took score 10 times and then took average of the speeds. This is the result:

(A) Site on DEDICATED in Canada:

From New York - 174 ms
From Texas - 685 ms
From Amsterdam - 1.04 second

(B) Site on VPS in USA:

From New York - 130 ms
From Texas - 432 ms
From Amsterdam - 1 second

So my questions:

(1) Why is (A) slower than (B) - it cannot just be geographic distance from the server can it?

(2) What is the best way to optimize servers for getting increase in response time?

(3) Can anyone suggest an awesome dedicated server provider with rates as competitive as iweb.com ?

if the pages have static content and are identical, i'd look not into the server's performance but into the network configurations, routing and net connectivity...

tracert both servers and comapre the hops....

1) Yes. Latency will influence your tests.

2) Tons of ways to do that. Check Pingdom and get your site speed score for options.. You could try using a CDN to deliver your content closer to your user given your current metric.

3) Sorry. I can not recommend anyone for adult.

1: Yes it can since it's ms.

As for a great host I can recommend Certified Hosting.
Great host, great prices :thumbsup:thumbsup

If youre running other things on server, it will slow down the DEDICATED right?

So also, what about the UNIX operating system?
Is CENTos slower than others?
Is one UNIX better for delivering pages Faster?

My DEDICATED is:

Intel Core2 Quad 2.66 GHZ
5 GB Ram
3 x 400 GB HD
3000 GB Band
100 MBPs Port Speed
Runs CENTos
Cost: $100/mo

Is there something I could do to really speed it up?

Would something like this be better:

Intel® Core™ i3-540
3.06GHz H/T
8GB
2 × 1000GB SW
20TB

Does 3GB extra ram make a big difference?

dedicated should be faster since you arent sharing resources with other people.

This is do to distance.

Your VPS is not bogged down. You can try using cloudflare and having it cached.

Provider A is slower than provider B. Provider B has better bandwidth.

Just spend a little more and go for a provider with a faster network, $100 for a server like that one is extremely cheap and it is logical it will perform much worse because most likely the network is oversold.

CentOS is a form of Linux, so is Debian. Linux is again based on Unix, real Unix does not really exist anymore in its original form. CentOS or Debian? I can tell you which one is best, but first you must tell me which car is best, which song is best and which color is best. It's just an opinion.

Oh by the way, the dedicated server with 3 drives will outperform the VPS any day once you start using PHP and MySQL. Try a benchmark test, if it takes you dedicated server to crunch a fully loaded Wordpress site in lets say 1 second, and deliver it over the network in 800ms, it is still faster than your VPS which would be chewing it for lets say 3 seconds, and deliver it in 500ms.

VPS is typically a dedicated server running some kind of virtualization e.g. XEN, OpenVZ, Vmware so that you're sharing resources (HDD, CPU, RAM, connection) with others. Some providers do oversellling in which case one dedicated server runs hundreds of virtual servers (VPS), but if you're lucky you can get a decent VPS which is not overloaded.

For static content, page loading time usually depends on connection latency of your server (assuming connection / hdds are not overloaded). Since all users will not have the same routing to your server, it may seem slow for one person but fast for another. You can check latency of your server from various locations here: http://lg.he.net/ (select ping, lower ping = better).

It's hard to say what kind of hardware you need without knowing what kind of software you're using (apache, nginx, mysql, some 3rd party soft maybe?) or how many clients you have.

Any professional hosting should be good for hosting adult content if you choose a dedicated server option (just check TOS to be sure). I can recommend OVH, leaseweb.

Provider (A) is of the biggest provider in Canada which is another reason why im wondering....

Not saying iweb is a bad provider, but hosts like that focus more on quantity, less on quality. Lots of cheap sales, bigger server farms per admin. iWeb has low prices, but enough money for advertising. Makes you wonder where they cut the corners.

Edit: I wouldn't worry about it too much. The difference in latency is minimal. Low ping is important for gameservers. Waiting for 0.02 seconds longer for an established connection can be neglected. As long as the network is stable and there aren't huge swings in latency.

Our VPS are generally much faster than a lot of dedicated servers, and it has really nothing to do with bandwidth ...

Most of our dedicated servers are configured with RAID1, RAID0, or Linux software RAID ... but ALL of our VPS offerings use a 6-disk RAID10 redundancy ... so the disk I/O on the VPS is at least 300-500% better than a dedicated server with common 2-disk configurations.

With the shift in recent technologies, we have had many clients previously on a dedicated server, make the switch to a well-appointed VPS. And with Google giving the most love to sites that load quickest nowdays, you want as high an I/O rate as you can get!

Most of our clients who choose to stay on dedicated machines, are either A) old-school webmasters who still believe that VPS is only a bridge from shared hosting to dedicated -- or B) running scripts that require unconventional server configurations that cannot be setup on shared hardwares.

A large site utilizing a CDN setup, is also a series cluster server setups - similar to VPS.

That being said, yes you will in some cases see a much better speed with a VPS than you will with many dedicated servers, and it has really very little to do with the bandwidth.

Virtualization has improved so much in the past 5 years, that I have even unfortunately seen some "Dedicated Server" companies sell 'virtualized dedicated environments' as dedicated servers -- as they tend to be much more cost effective when you share the hardware with multiple users -- and 90% of webmasters will never know the difference or be any the wiser.

If you want great support go with NatNet for dedicated server.

check pings from same location distance for start, it could be latency from god knows what reason

tried just-ping.com

Disk i/o rises somewhat incrementially with the amount of containers per master node. You can check your I/O wait percentage via top (CPU % wait is your I/O load). Try this command, it should give you a result similar to this one:

[root@master ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 34.3023 s, 31.3 MB/s

Anything below 20MB/s is very unusual. FYI, RAID1 mirrors contents over 2 drives. 2x 250 GB makes 250 GB mirrored on 2 drives, which has faster read speads but obviously the same write speed. 2x RAID0 makes 500 GB and different parts of data are written accross the 2 drives simultaneously. It has faster read AND write speeds, with double the risk of a drive crash. RAID5 does not have that problem due to added parity but requires 3 drives.

So make sure your server has the right RAID configuration, and obviously hardware RAID is better than software, make sure which one you have so the benefit of your 3 drive server is not wasted.

https://developers.google.com/speed/pagespeed/service - Is a pretty good service that is similar to CloudFlare - At the moment it is free but they have said they will charge in the future...

While reading some ads about VPS you can get an impression that VPS is so great that running a virtual machine inside a virtual machine inside a virtual machine ... gives you a perpetual motion ;-)

there are still plenty of Unix-like systems dumbass.

either the dedicated server is miss configured or the network sucks.

Care to explain? BSD is dead and MacOS is tablet software. Even Android is based on Linux.

also no one mentioned if you have ssd on your machine it will respond faster and perform faster in some situations, specially when its on vps.

BSD is not dead besides being used on servers its use for the ps4, tv's and other devices.

IBM sells more unix systems in a year then your shitty hosting company will sell in its lifetime.

Stick to bumping year old threads and reselling burst.net servers.
