RAM Usage: Dedicated Server Vs. VPS
May 1, 2009
I have never rented a dedi before but have used and continue to use VPS for my websites. With a hostinabox VPS with lxadmin control panel and apache for web serving I have seen idle ram usage at around 100MB. My question is am I going to see a similar amount if I move to a dedicated server ? I ask this because I remember reading somewhere that dedis have a higher RAM usage by the OS compared to VPS. So does a dedi at idle use more RAM than a VPS at idle?

I'm currently running vBulletin & two wordpress powered blogs on my box. Number of simultaneous users is about 200~250 and about 15~20 logged in users.
The memory usage is constantly in the range of 1.8 GB - 2.00 GB. Considering that total physical RAM my box has is 2 GB, the memory usage, I believe is exceptionally high.
The same site was running very well on shared hosting environment and also on VPS [with just 512 MB RAM] very fine.
What should I do to bring the memory consumption to minimum (required to run the site well?)

Since a short while back my server memory usage is 100%. The amount of
visitors decreased so the memory should be lower in consumption than before.
I suspect a newly installed script could have bugs or misuse of the
server by hackers. I don't know how to see on the server what script or
what part makes the memory use so high. I see Apache is very high but
I'm on VPS.
Technical data........

I have a dual quad xenon server running Linux that will be used for a video sharing site. Currently it's set up for testing.
I have the impression that although the encoding software is able to use all 8 cores simutaneously I'm not convinced that is what's happening. Can someone suggest software that would show all 8 cores displayed individually in a graph. Something like the way task master on a windows machine does with the performanc tab showing cpu usage. And the second part of the equation is can I delegate for example 6 cores for encoding and 2 cores for streaming the videos?

Currently i have a small server with 512 Mb of ram i doing some minor hosting..
sometimes..my free memory is only left with 15 mb..is there a concern down here?
is there anyway i can find out what are using up my memory..? And should i just upgrade to 1Gb instead?
Somtimes my mail queue ..will also take up like 20 to 30 mb of memory as they keep on trying to resend themself

I have a low traffic VPS, with fairly limited resources (most notably only 256mb RAM).
This runs fine for what's currently being hosted - one low traffic site (with 1-10 users on at any time, usually 2 or 3), and several other essentially dead sites. Everything runs smoothly, and generally RAM usage remains below the 200mb mark.
However, I've been contempating setting up a Subversion server on the same VPS, and I'm unsure if this will top it over the limit. Does anyone here have any experience running a SVN server? How memory hungry is it? If I do set this up, it won't be very active, with a couple of checkouts a day, and a max of 2 or 3 users connecting at any one point, more often than not no one will be connected. Can I do this with the resource limitations listed above, or should I start looking at alternatives?

For research can someone tell me what is the average transfer ratio for a game server (ie Inbound vs Outbound)
So if a game server used 200GB outbound. How much Inbound would this equate to?

I just moved from a P4 Dual Core (2mb cache) to a Dual Xeon (512k cache) and everything has gone to sh*t.
I had the server optimized/security hardened (for the most part) and last night, I had a RAM upgrade to 4GB.
As soon as the server came back up after the upgrade, CPU usage was into the mid hundreds. RAM usage is fine....
Presently, I'm showing PHP using a ton of CPU. I tweaked mysql a little bit, and that helped slightly.
Also, last night, I had the DC run diagnostics on the RAM and hard drive. Both check out OK.
Here's the specs:
2x Intel Xeon 2.80GHz
4GB RAM
cPanel
CENTOS Enterprise 5.2 i686
PHP 5.x
MySQL 5.x
Exim
When viewing TOP or status in WHM, php scripts use the most CPU. With average CPU load around 60+

a few times, my host contacted me and said that my account is suspended due to high usage of server resources.
I have 3 sites using SMF (a forum script.) I have around 8500 visitors and 3 million page views per month in total.
can this be a reason of high usage?
if it's what's the meaning of terabyte traffic limit ? which you can never use
I asked to my host if they could let me know what's causing high server resources usage. here is the answer:
We do not know which domain or script caused this high usage, it is your responsibility to investigate. I would suggest that you go through your raw access logs to see the most requested pages and then investigate those further. After you find the pages responsible, please optimize them so you are not using so many server resources.
so if a host wants simply to restrict traffic limit, they have a pre-reason under hand.high server usage! yes but how will I know that? how will I trust that it's true?
when I ask why my sites are down, they can easily tell me that it's because of high server usage!

I have server load like 40.
Nothing lags.
Server has RAM usage 20% and CPU usage goes up to 25%
Swap isnt used at all.
Should I be afraid of server crash incase server load goes up to 60 or 80 without ram and cpu usage rising that much?

My VPS host is (for now) still using LxAdmin, but is no longer allowing login to HyperVM for reboots and access to system info. Please, tell me exactly how to use SSH to check the current memory usage on my VPS.
Quote:
Viewing your current resource usage
Log in via SSH, I normally use the Putty client for this.
Commands:
top: your current server load & resource usage.
ps aux: all your processes & which ones are using the most memory/cpu
free -m: allocated memory, usage & free memory
Is the command line really *easy* once you get used to it?

For the past few days, one of the server is causing a bandwidth utilization surge for the entire rack on almost daily basis. It happen for a few minutes and it went off then it will be the same thing again the next day. When the surge is happening, most of the servers on the same segment will be inaccessible for the few minutes.
The bandwidth utilization graph for my rack is recording an abnormal surge from (6mbps --> 90mbps) for the few minutes. My MRTG is showing 2 of the Plesk servers giving the problem but the NOC guys said it the Cpanel that causing the problem.
I tried logging in to both servers but could not find what's the cause for this.

I am currently using a shared hosting but due to increasing traffic and server load my existing host is not able to provide reliable services and I am planning to upgrade my hosting service.
While I was searching for Dedicated Servers, I learnt about Virtual Dedicated Servers but I am not very sure about their reliability? Are Virtual Dedicated Servers useful? My website current serves over 2500-3000 visitors a day resulting in 30,000 pageviews and I am expecting the traffic to grow by atleast 2 folds in the next few months as I start some PPC campaigns and Email Marketing for my website. Can a Virtual Dedicated Server cater such needs assuming my website to be more of less dynamic website written in php?

I have Plesk 11.5 (service provider mode) on a Windows 2008 server IIS7.Most of my sites are developed in .asp and therefore i use a custom 500-100.asp error page that check s the IP of the visitor then displays either a friendly error, or if its my IP a full error of what has happened (it also emails me the error). This allows me to debug pages easily whilst developing and to keep an eye on anyone trying SQL Injection hacks on my sites (as the error and email also have session variables and IP address).I dont have root access to the server as it is a Webfusion dedicated server.I have following the Plesk documentation -
1) Switch on custom errors for the subscription
2) Look in virtual directories and navigate to error documents
3) Find the error in question (500:100) and change it to point at either a file or URL
FILE - I had the data centre add in the 500-100.asp error page in to the virtual template so that my page is available in the list of virtual files - this didn't work but that maybe because its not a static page??
URL - when i add the path it says its incorrect, if i add a fully qualified address, it accepts it but it doesn't work.give me a specific example of the URL that can be entered relative to the root as the format in the documentation isn't accepted. The last step is to restart IIS which is also an issue as i cant seem to do this from the Plesk panel..It is as if it isn't catching the 500:100 error, and only catching the general 500 error??

I am going to be buying a dedicated server from kimsufi Most likely the 2XL Package.
My streamers will be using my server aswell, On weekends we will be running 3-4 streams at a time, weekdays 1-2 at a time.
Spreading all the streams out, at anyone time we will have 300 viewers.
I need to know your advice on this before i go spending money.
How do i convert my dedi into a flash media server, i need red5 or something, thats all i know so far. My streamers wil be streaming to server with FME, And i also want it coded so that my streams can only be embedded on my site.
Basically i dont have a clue where to start, how long would it take me to set up etc....
In addition, what kind of server do i need, windows / linux / traffic / burstable / standard etc..

I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.

I'm a a JAVA software developer and it happens that I need to configure a dedicated server running Win 2003.
It's already up and running with static IP address, however hosting offers a "Static IP Address", which doesn't really make sense, cause I already have one?
Other thing is domain name. Current domain name is registered with a different company and we don't really want to transfer it from that company. Can I get away with importing a domain name and changing MX records in the domain control panel?
Last thing is an email server. What do I need to set up an Email Server? I have a domain name with few POP3 email addresses. I thought about using hMail server for windows. What else do I need to do, pay for?
