What factors do I need to look at in determining the proper setting for thread_concurrency in my.cnf running on a virtuozzo VPS? Processor threading as per usual or barrier values under /proc/user_beancounters?
I commented it out entirely a while back because I was I was hitting the privmpages limit. I forgot about it because I'd been having acceptable performance. Now it it's occurring to me that I could maybe slowly take it back up.

As you can imagine it is daunting trying to filter out the reviews of various webhosts on this forum. For someone who has not ruled out any webhost for hosting his business website, the time it takes to do appropriate research can be very time consuming.
I was wondering if there was some meta/uber thread that has a bunch of webhosts on it with a general rating for the host, maybe a "percentage approved" scale or something.
Or am I resigned to reading a bunch of threads?

I find that lots of hosts don't put the link to a phpinfo() script on their websites, even though that would save everyone a lot of unnecessary questions.
So I figure we should have a thread where people can add links to phpinfo scripts on their own hosts, or hosts where they happen to have the URL of a phpinfo script.
For those of you who own your own web hosting services, here's a chance to show off all your installed goodness, and all it takes is placing a simple link here (and put one in your FAQ section on your web site too, for the love of God)..
Since the forum doesn't allow editing your own posts (I still think that is nuts), please include all previous links in your post, so visitors will only need to read the LAST post to find all the updated links in one place.

I've been having trouble the past few days with someone who's been "attacking" my site so to speak by continuously downloading very large files with as many connections as (he) can open. I operate a large downloads site for computer games, this person has selected the largest files (like 400-500MB). Not sure of the real intent other than to clog up my bandwidth capacity. Also he appears to be using proxies since as soon as I ban one, another shows up seeminly from China.
Anyway, I have mod_bw and I've limited the number of connections in the downloads area to 2. While that works ok, his tool uses threads like a download manager would and he's using up 30-40 child threads for his 2 file downloads.
So 2 questions,
Is there anyway to not only limit file downloads to 2, but limit the number of connections per request? Many of my visitors do use download managers and I'd like for them to continue using them but use a reasonable number of threads like 6 or 8, but not 30.
Also, is there a way to restrict access to someone using a proxy?

Customer has requested the following:
"Create a zend id for your machine." This is apparently for them to create a product key for their software and have to bind to it?!
I have never heard of this and have been unable to locate any information on it.
This is a Centos box with php 5.2.5 installed:
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies
with Zend Optimizer v3.3.0, Copyright (c) 1998-2007, by Zend Technologies
how to go about this or even what this is?

After speaking to a colleague about some major benefits of EC2 for on-demand hosting I've been very interested in learning more.
I've spent the past 2 evenings trolling through Amazon Doc's and blog posts and have a fair assessment about how things work but I'm at a stopping point.
There doesn't seem to be a dedicated EC2 area here on Sitepoint and the Amazon EC2 forums seem geared more towards 'advanced' users.
Are there any reliable communities that are more for the beginner?
I've got a LAMP webserver Instance running on EC2 but I'm very unclear about how to login and begin adding files and managing the data. I'm sure it's pretty simple but the documentation pretty much loses me when they start discussing Security Groups and public/private keys.
I'm not much of a server admin but have grown pretty comfortable on our FC4 dedicated boxes that we currently host on.

I am sending out an email blast to about 30000 addresses when I leave. Because this is the down-time for our site, is it possible to temporarily give Exim more resources to help process? Or would this even be beneficial?
If both questions answer yes, please let me know where I should look for instructions on doing this.

One of my servers keep overloading due to a SQL process.
The process is:
/usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/zeus1.forcium.net.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock
It takes up pretty much 90-95% of the cpu and memory at times if I do not kill the process. But even after I kill the process it comes back and immediately hogs up cpu load again causing it to go into loads of 8.00 or higher ( I have 8cpus ).

I'm guessing it's a no but if I start a VPS and it starts to eat ram or I think it needs more CPU can I just increase it? I'm talking about using OpenVZ.

We've just started to use a VPS, and so far no problems I've been looking at the resources and they seem a little high considering it's pretty much out of the box, and I've only setup 4 sites which aren't even public yet. The only thing I've changed is the php.ini to increase the memory limit to 32mb. My main concern is that these sites don't suffer when they go live.
In the Plesk control panel the memory says:
3.8 GB of 3.8 GB used; 47.1 MB available
The 47.1mb is pretty much average, although I've seen it go as low as 115mb.
In Virtuozzo the system usage (resource: capacity) is usually around 60-75%
Both of these seem a little high, but I'm not sure if these readings are for the whole physical server, or just my portion of it.
Also in the (Virtuozzo) QoS alerts I've had quite a few Yellow zone, black zone and one red zone reports, at around 5am - quite possibly the quietest time on a server which isn't hosting any live sites yet. These have both been on the numproc and the privvmpages services (the red zone was one the privvmpages). Is there anything I should be looking at or is this fairly normal operation for a VPS? I have nightly backups scheduled for around 1am. These were originally set for 4am, but reports were showing that they were running out of memory, so Ive now staggered the times of these to see if that helps. I've haven't changed anything resource-wise other than the php, so I thought it would be good to go from the start, but maybe it needs some fine tuning.

Is there a way on a Virtuozzo server (via. SSH) to check how much CPU or load/cpu-resources each container is using? Or some other way?

We have a Dedicated Hosting Account running with the following configuration:
QTY Hardware Component
1 Supermicro Dual Xeon SATA X5DPA-TGM
2 Intel 2.4 GHz 533FSB P4 Xeon
4 Generic 512 MB DDR 266 ECC Reg
2 Western Digital 160GB:IDE:7200rpm 160GB
1 Unknown Onboard IDE
Installed Software
- Urchin Urchin 5
- Redhat Enterprise Linux - OS ES 4.0
- cPanel, Inc. cPanel STABLE
We are using Exim for the mail server.
The Server Load reaches upto 35-40.00 every now and then and apparently Exim eats up most of the Resources.
I am attaching a few Screens with the output of Command line top and the WHM Process Manager.
You can see there are a lot of exim Processes/threads running.
how to Optimize the Server for this.

I wanted to know a rough estimation of resources needed for a download server with these specifications..
1- No cPanel needed
2- Unmanaged plan
3- VPS or Dedicated
4- Space needed -- not much . maybe maximum 20 giga
5- Direct links with no software to upload or download all is done through FTP and HTTP browsing
6- Bandwidth / month more than 300 giga and less than 600 giga ( can compromise ) .
7- maximum simultaneous downloads will be 10 - 20 individuals on the same moment
8- Files on server wont exceed 30 mega per file
How much Ram/CPU mainly I may need?

I am running CPanel/WHM as well as the WHMSonic plugin for a Shoutcast service. Now the thing is that my RAM limit is 4GB, but my RAM usage is always at around 3.5GB and above.
I guess it's mainly due to WHMSonic, so is there any way i could lower this RAM as on multiple occasions the server has locked up and shutdown,rebooted or had to be rebooted.
On top of that, the server load is around 10.00 or above.
Is there a resource controlling script which i could install?

I have seen some requests for cheap Virtual Private Servers. By saying "cheap" I mean under $20/month... However the those who posted the requests meant under $10/month...
I don't think that a virtual machine or container would cost $10 or less, but I've seen some providers to offer virtual servers with a very small amount of resources - a couple gigs of space, not to much bandwidth and 64 MB or 128 MB RAM - and to price them around 10 bucks per month.
Although I'd never go this way I'm curious to read what do you thin about such a marketing policy. Do you think that offering a VPS which can not even have a control panel because it doesn't have enough resources is a good practice? (I realize that there are different scenarios and some people probably don't need hosting automation software, but at the same time need a low cost virtual machine...)

I got a dedicated server running, which is administered by DirectAdmin, which I mainly use as a mysql server. Now my question would be, what would I do to give all resources possible to mySQL? I mean I donīt wanna take down directadmin and setup mySQL only, so I want to keep directadmin but give almost all server resources to mySQL?
What I did so far is adjust all tables, do indexes and stuff.
The background is that at certain times I face server loads of 40 caused by many external servers of mine querying the mySQL database on the server I am talking about.
So while the load is mainly below 0.1 it sometimes goes up to 40. So this peak I wanna slow down a little bit by giving all resources to mySQL. To say that beforehand splitting the queries from external servers is not an option - they all need to be done at the same time.
So I would really be interested and thankful in what you would advice to do to optimize the mySQL service?
BTW system is running on debian.

I have a VPS where i have cpanel installed. I have noticed quite a number of times through my WHM Cpu/Memory usage that there are 3 instances of MRTG and they seem to be taking up a lot of resources.
I did not install mrtg and i don't even know how do i go ahead and view them
Can someone tell me how do i remove them and is it just me or are there actually 3 instances of MRTG running for everyone?
Here's a screenshot of the same:
