how many concurrent users support a p4 3ghz with 2gb of ram?
server is running about 10 sites using php/mysql and when there are 30/40 concurrent requests on apache2 the cpu load go to 5/6 until 10 in some cases
is this normal? i need to upgrade my hardware or i need to optimize mysql/php/apache?
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.
75000
150000
225000
300000
400000
500000
I am planning to set up a forum. What kind of server do I need? I am expecting to
have
- 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?
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.
Like the topic suggested, anybody have a rough estimate of how many concurrent users game websites such as wildtangent and instantaction have? Also, what kind of server configuration would be necessary to support those kind of users assuming you have 1 server for web and 1 for database.

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
12GB DDR
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.
I know this sounds a difficult question, but any rough answer is better than none. I am sure there are rough expectations.
Will it be 10's, 100's, 1,000's, 10,000's etc.
I am looking at a dedicated server Intel Pentium Dual Core 2.0GHz, 1GB memory with network speed of 100mb (with gigabyte burst whatever that means).
[url]- bronze package - if anyone is interested)
I will run one site only. The site has very heavy database usage and normal page views with average images.
Video / most photos are hosted and delivered with a seperate, top-quality CDN.
Your answer might be... "You should get about 1000 surfing, using database etc. before you notice a slow down" etc.
I suppose the thing is.. at what stage would I need a second dedicated server / package upgrade / what will this server get me?
What is the fastest server Dual Xeon 3.06(HT) or Pentium D 3Ghz ?
to select the fastest one?
Dual Xeon 3.06 with HT
512K cache [1MB total on 2 processors]
533FSB
2GB Ram
Pentium D 3 Ghz (Dual Core)
2MB cache
800FSB
2GB Ram
==================================
My second question is,
Pentium D 3GHz mean
1.5GHz X 2 = 3GHz or
3GHz X 2 = 6GHz ?
The upgrade has an error when manage the users database.

PROBLEM DESCRIPTION
In a costumer panel have a one database MSSQL, and assign to this DB 3 users, but the tab option "Users" don't work fot his costumer and show this error:
Error Javascript:
TypeError: template is null
this.template = template.toString(); in protototype.js 8472831 (lÃnea 807)
ACTUAL RESULT
Error Javascript:
TypeError: template is null
this.template = template.toString(); in protototype.js 8472831 (lÃnea 807)
EXPECTED RESULT
Show users in the tab users for database.
i have a vps, and im current use lighttpd, but i want move to litespeed Standard. And i see they limit Max Concurrent Connections =150 on standard version.
but what is Max Concurrent Connections? where can i find it.
and is it the number connection via port 80 (netstat -nt | grep :80 | wc -l)?
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)
Iam currently on godaddy on shared hosting but my site with php and mysql is very slow on queries and get a lot of timeouts
So far i have contacted the below providers and asked them how many concurrent connections on mysql database they support
hostgator - 25 connections
powweb - 20 connections
hostmonster - 30 connections
Servage - 20 connections
anhosting - 50 connections
How is most reliable and i can count on ? I want to tranfer my domain.
Is there any host with a shared connection that will allow Unlimited concurrent connections to both http and to mysql.
I Got a myspace clone that just blows through connections when my users are logged in.
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?

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.
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.

Is it possible to limit the max number of concurrent access to an url?
Let's see the following example: URL...
/a1 concurrent access should be limited to for example 20.
While we have an other url:
https:/ssss.com/a2
/a2 should be limited to 30.
Is it possible to do it with some apache config?

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":

Has anybody heard of Flash Support and Real AudioVideo Support? MMHosting.com offers this kind of support and I wonder if it's effective?
What do you think of it?
I'm undecided between an upcoming dedicated hosting server and am moving between Softlayer and ThePlanet. My decision partly comes down to support.
I've read many reviews on WHT about both companies, but not necessarily comparing them from people who have experienced both.
So my questions (keep in mind this is my first dedicated. I have used VPS in the past with good support) Which offers MORE support (not better) - I'm curious which company might consider my support questions as "part of the default service package" or "need additional service plan for that" More detailed support - my usual experience with support is support staff assume you already know a high level so it may take going forward and back 5 times via email to get a full answer
Overall support satisfaction - any other comments
I've been with Hivelocity for 2 years. Occasionally we have problems, but it works. Their support staff can do very simple things relatively fast, however if you have some serious problems, e.g. failed disk and need to be replaced and do restoration from backup, it will be hell!
They will NOT do what asked in Reload Request, delayed answer to chat, no answer to tickets for many hours.
So far I'm very disappointed of Hivelocity support.
im on a vps and enabled ssh to other accounts but how do i know whats the loginid n password for it?
View 5 Replies View RelatedI have a few system administrators having full access to the Windows 2003 servers. I fear some of them might be messing up with the server like opening websites on the server or downloading files on the server. I want to create unprivileged users to login to the server so that they can do the basic tasks like reading the log files etc. Can anybody give me the steps for the same?
View 0 Replies View RelatedI've searched around these forums (VPS specifically) and cannot find any recent "reviews" or opinions on HostDime's VPS offerings.
Anyone using them? They seem to have the most bang/buck and I'd like to get a more recent review opinion on them.
we have a WHM account... we have different accounts on that...and for each account, there are add-on domains underneath that. (i hope you know what i mean)
and we set it up to use only SFTP to connect to server. no FTP.
after we have set it up that way, it seems that we can only connect to SFTP using 1 user/pass for each account... that is the same user/pass we use for Cpanel of each account.
say, i have Account A... under Account A, i have addon domains: A1.com, A2.com, A3.com...
setting SFTP only on that server, all those addon domains of Account A, can only use 1 user/pass to login to SFTP which is the cpanel access also of Account A.
question is.... is this behavior correct??
how can we create a different user for each add-on domain?
How can see mysql users and how can change password for a user.
For example www_user (mysql user) in shell access?
with webmin can I use it to add FTP users to say pure ftpd? and does it work with lighttpd? If I'm thinking about it right webmin just allows us to control the service and modify the configuration files right?
