A friend of mine has a VPS server from godaddy, the site he is hosting on this VPS is quite slow and times out a lot.
What would be the best option? Move out of godaddy? Upgrade the plan? or hire someone to optimize the server (apache/mysql).
If you would recommend the third option, it would be great if you can let me know about companies that provide this service.
Are there some simple things that we can do or perhaps request our server management to do to optimize our server? Not sure where to start or what to ask so would like to learn some more before speaking with the server management company. Often times, you need to know the right questions to ask.

I am having problems with apache going down at least once a day. In Plesk there is a watchdog that monitors the service and then restarts it, but tries 5 times and fails, so apache will still be down and monitoring released. I really don't know what is causing this problem, maybe I could get some help? (Server specs at bottom of post, hope this is all you need)

i have a Pentium D 820, 2GB Ram at LT where i am hosting a few proxies. Using Centos and Directadmin.
It's realy fast and i am happy with it. The only problem i am facing is that load is jumping up to 60 sometimes but just for a few seconds. Especially when a lot of people are using the proxy and it slows down a bit. That affects only the proxified pages and not a few personal html sites i also host there.
At the moment i am seeing in top that the CPU usage varies from 0,2 to 8, 12, 21 etc but just for a second or two
here is the top output

is there any way to tweak or optimize the server so than it can cope better when a lot of people are using the proxy.
it's getting to the point where I need to optimize MySQL to better handle a busy server.
These days it seems MySQL is using 30% - 60% CPU almost constantly. But, the good news is that I've got 4 gigs of ram on this box and their seems to be an access of 600mb free constantly throughout the day.
Is it possible to tweak MySQL to a little more RAM dependent and take some of the load off the CPU? It seems MySQL wont go over 300mb of ram at any given time.. I'm already working on optimizing the SQL Querys on the web page itself.

Are there any services where an ADMIN can monitor DB usage on system and make some recommendations or even find SQL that is poorly written ...
I have a DUAL harpertown, 10GB RAM, and RAID
I have a typical, gallery, busy VB forum, and video script...
THe site traffic has not increased much but my Memory keeps getting chewed up... i already did some tuning that VBULLLETIN suggested... but the memory still goes... i need a tool or someone to just monitor the server for a day and grab as much diagnostic info as possible..
I suspect that its a single query giving problems cuz i have some custom coded pages...
I don't want to split the DB and HTTP request on diff servers cuz the traffic that i get shouldn't warrant it... for now...
I have a 512mb cPanel VPS and would like to try and save a bit more ram, I have made the below changes to the httpd.conf and have also turned spamd, entropychat, melange, mailman, the only webstats I have is AWStats
Code:
MinSpareServers 2
MaxSpareServers 5
StartServers 3
Can anyone recommend any other changes to save some more ram ?
For anyone wanting to know, the VPS is being used to serve my websites
I am wanting my VPS Optimize to run at it best

I wonder if I can change anything to make site is faster? Currently, it's very slow. It's one core2duo box with 2GB RAM
i run a popular forum with at least 1000-1200 users online at any given time which reaches 2000-2500 at peak times...
i am using Invision Power Board.
Problem:
Server seems to lose connection with mysql server at peak loads with server load going upto 30.
The server is good enough for these type of loads...

I remember seeing a website/forum where you couldn't post your server stats and httpd.conf settings and experts would give advice on settings you should use.
Does anyone know the url to this site, or site similar to it
I optimized a mysql table of 2 million records and about 500MB.. it took about 15 minutes.. However, on the same DB now i have another huge table of 88 million records, it size is 2.2 GB and it has about 30 MB to optimize... my questions..
1.- How can I speed up the optimization process so it can take the less possible time? any tweaks to my.cnf?
2.- Should I repair it using phpmyadmin or just from the shell?
3.- Should I stop http traffic during this optimization?

We'd like to use this tool from Google on our Plesk server: [URL]
is it useful getting these tools going on server, and are they worth it?
I have four servers with a quad xeon, 4gb ram, and 2x300GB SAS 15K RAID0 harddrives, pushing a total of 1.6gbits. It serves a lot of zip files with an average flesize of 180mb. My question is, how can I optimize lighttpd 1.4.19 to push its max with very low IO-wait. I've looked up some stuff and only found options that deal with lighttpd 1.5 and use Linux-AIO for the backend network. Currently I use writev with 16 workers and an read/write idle timeout of 10s. Logging is off, too.

Approximately 30 queries a second - constantly. That's over 2.5M queries a day -- so we are talking big (I think?)
I am currently running this test on a
AMD Phenom 9300, 4GB RAM - SATA 500GB HDD and I am running MySQL 5.0.51a i386 on CentOS
I have programmed a process control for our applications purpose - basically it controls the launching of our SQL intense applications, and stops launching when the Load is greater than 2.5
I have plans to optimize the number of queries (I will build in a cache to some of the applications - and run INSERT statements all together) however I am looking for SQL tweaks that will improve performance. Would running the 64bit version work better?
What I did here was create /var/log/mysqld.slow.log for queries that are taking one second or longer. After around 36 hours, here is what I came up with. Since the file size of /var/log/mysqld.slow.log was 219KB, posting it in its entirety it not practical. Therefore, I used a program, the perl script known as mysql_slow_log_parser found on www.retards.org, to parse the mysqld.slow.log to make it easier to interpret and read. The result was that the original filesize of 219KB was converted to the smaller size of 14KB....

What I've got running:
Apache2, PHP5, MySQL5, Dovecot, Postfix
One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.
Changing the server software is not an option - Only optimization.

I looked a lot - can not find solution ....

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 currently running Google Analytics/Urchin 5 (v5.7.02), on a server, the server has started to act up, (on its last legs etc) and now I am trying to transfer the Urchin Software to a new server, where it would work effectively.
However upon installing the urchin software on the new server and running it (localhost:9999), I am presented with An Action Items Page, and these following choices
Obtain Demo License
Buy License
Activate Pre-Purchased License
I choose ‘Activate Pre-Purchased License’ pop in the Serial number and complete the registration then…
---------------------------------------------------------
Urchin Licensing Center -- Error!
An error has occured during your transaction, please use the back button and correct the problem. The specific error message is:
• Unable to generate a license. Some possible reasons:
Your serial code is currently active <<< How do I disable it and use it on another server?
---------------------------------------------------------
So all I want to do is deactivate the serial and reactivate it on another server.
Does anyone have experience with this or a similar problem or have a solution to this problem. Any help be most appriciated.
Or even a Contact Number so that i can get some one over the phone!
This is the scenario, domain.com are setup on server1, however server2 also has the same profile of domain.com as we use ns3 and ns4 using domain.com. This works fine with the nameserver setup on server2.
However I encounter problems as the emails from server2 won't reach server1 as there are duplicate profile on server2.
My question is how do I setup the DNS in cpanel/whm from server2 so the emails from server2 will reach server1?
Server1 (www.domain.com)
ns1.domain.com
ns2.domain.com
Server2
ns3.domain.com
ns4.domain.com
I just want to use a server for file sharing, it will have nginx and that's it. I'm looking at centos, or freebsd, but I been using centos forever now and I'm not sure how to use freebsd, should I just stay with centos?
Do I tell my hosting provider to just install the OS and give me ssh action and that's it? Don't install any control panels or any other stuff? I want one domain and one subdomain on it though and ftp action.
