Hosting / Number Of Concurrent Users

Apr 2, 2008

I am planning to set up a forum. What kind of server do I need? I am expecting to

- 40-50 concurrent users

Do I need a dedicated server (2 GB) - which would cost me about - 350$ per month - or is it

possible to find a cheaper solution?

How Many Concurrent Users On The Average VPS Plan

Jul 26, 2008

I'm on a vps using Dell PowerEdge Servers and 750 GB of transfer.

I have concurrent users settings to where i now have them at "50" and I'm wondering how much higher i can go without troubles.

My app is a perl cgi script in flat files and 95% of visitors will pass through my domain without seeing my webpage. They are only there approx 1 second, maybe 2 as they are quickly redirected from this platform.

My host has a custom solution installed to check for apache stalls every few minutes and it will restart apache when it sticks - and it will stick from time to time.

Just now i do about 75000 per day but plan to double to 150,000 next week and soon after will triple to 225,000 visitors per day.

Should i increase concurrent users now in prep for the increase to 150k or at what level.

Please give some suggestions for concurrent settings at future traffic levels. This host has a multiple server set up in case one fails - i should be good, i think.

I try to search and not found the solutions to limit concurrent of db users to connect to MySQL in same time for example:

Limit user root to connect to MySQL maximum 5 connections in same time

There have max_connections setting but it limit for all users in all connection to MySQL.

But I found that in version 4.1.x there have max_connections property in user table (Users and global privileges) of mysql database, this setting is limit connection in 60 minutes.

I would like to know if there any setting or code modify for this solution that I want.

Maximizing Linux (CentOS) For Maximum Concurrent Users

Jul 28, 2009

I am running lighttpd and eccelerator.

I have stripped the php-cgi.

I have tried forking anywhere from 50 to 300 to 1000 fastcgi children with PHP_FCGI_CHILDREN (through lighttpd, I'll attempt to do with same with spawn-fastcgi and fpm)

Server stats:

Intel Core i7 920
250GB 7.2k RPM SATAII 16MB Cache

I am using to lighttpd's lighttpd-status to estimate concurrent connections.

When I refresh the panel, it shows that there are around 100-150 connections and around 150 requests/s in the last 5 seconds.

My vmstats show that CPU is 98% idle. Blocks written/read is neglible. MySql key_buffer set to 2gb and I'm pretty sure it's not mysql. The overwhelming majority of requests do not access mysql.

EDIT: Uh oh, I just realized that tcp_mem could be a huge bottle neck.

I just set it to:

net.ipv4.tcp_mem = 4096000 87380000 4194304000

It was previously:
net.ipv4.tcp_mem = somenumber somenumber 393,216 <<<--- WTF!

x1000 for my read values (it's an access server only). I can't benchmark the server right now so let me know if you have any suggestions besides this. I do think that this was the problem. When under load images could not be accessed either.

Show Number Of Users Connected To Server

Feb 23, 2007

I've tried the uptime ssh command but that only shows how many users are currently connected to the server via ssh. Does anyone know a command to show how many active http connections there are? I'll use php to run the command and print it to the users browser so they can see how many users are on each server. Very similar to what gamershell do.

Hosting Without Number Of Email Restriction

Nov 20, 2007

I have a custom made server side bulk email application. My current hosting service does allow unlimited emails (most restrict to around 3-500 per hour) but im having other problems with them.

As such I need a new host for this tool. I send around 45,000 emails as newsletters to my site members about 10 times a year.

I know that a dedicated server is a obvious solution but I dont want the management headaches and higher costs that go with it.

Has anyone got a shared hosting solution that doesn't restrict email numbers or atleast has much higher limits?

Oct 5, 2007

I'm new to Private Virtual Server and the package offered by different company are quite confusing.

I was on RackForce and their basis VPS package dds200-L can host 100 domain names on Plesk and unlimited domain names on WHM/Cpanel.

On 1and1 it didn't say if Plesk support 100 or unlimited domain names. My question is, do we always have the liberty to host unlimited domain names on our PVS?

Can anyone recommend a good VPS hosting company?

Preventing Users From Connecting To Other Users Database

Mar 25, 2009

On my server, users can connect to any database as long as they have the database user and password. This makes it easier to hack any database on the server.
What I want to do is to make the users can only connect to their own databases and not other's.

I tried changing the localhost ip address but it didn't work ( I assume I didn't do it the right way)

15,000,000 Concurrent Sessions Using Only 2 Dedicated Servers

Jan 10, 2009

I was looking at some load balancers hosting companies offer and some of the load balancer specs say they can handle up to 15million concurrent sessions(users online at the same time), so does this mean if i had a site like wikipedia that had 15 million users online at the same time, would i be able to do this with only 2 dedicated servers, or will the Cpu's not be enough?

Linux Cisco VPN Client - Two Concurrent Connections Possible?

Jun 21, 2008

Server: Dell 2950
onboard NIC only
CentOS 4.6

Is it possible to run two concurrent VPN connections using the Linux Cisco VPN client? We need to have one server be able to communicate over two different vendors gateways.

Do we need to possibly add an additional NIC to the server first?

When we try to connect to another profile we get the error:

Initializing the VPN connection.

Secure VPN Connection terminated locally by the Client

Reason: A connection already exists.

[Apache2] Enable/disable Concurrent Connections

Apr 28, 2009

Currently I use WHM/cPanel latest on a few boxes, I have (at least to my knowledge) copied the exact compile settings between servers, yet some of my servers allow me to do concurrent file downloads (using DownThemAll or another "accelerator") whilst others only let me make 1 connection. These servers also don't show me the final filesize while downloading. So my question is, what did I set/unset to cause this to happen? It's been bugging me for a month or so now and no amount of recompiling has fixed the issue (aside from a clean install of the OS/cPanel). I can provide a list of modules and other config settings if required.

Plesk 12.x / Linux :: Concurrent Visitors Max CPU Multiple Php-cgi

Jun 25, 2015

I am running Plesk 12.0.18 on Centos 6.4

I have noticed that the CPU on my VPS maxes out. This occurs when there are many concurrent visitors to any of the 7 domains. 6 of the domains run Wordpress and 1 runs php-bb forum. When I run top during high cpu I see multiple "php-cgi":

32664 xxxx 30 10 211m 38m 8228 S 21.0 0.9 0:03.70 php-cgi
32675 xxxx 30 10 209m 38m 7992 S 25.8 0.9 0:02.08 php-cgi
30809 apache 30 10 422m 98m 2492 S 8.8 2.2 0:18.07 httpd

Looking at the process

32664 ? SN 0:01 /usr/bin/php-cgi -c /var/www/vhosts/system/

The net result is CPU hits 100% and visitors are greeted with Service Unavailable ...

Output from /usr/local/psa/bin/php_handler --list

id: display name: full version: version: type: cgi-bin: php-cli: php.ini: custom:
