I'm having trouble with a new server. It's a dedicated (Q6600 + 8 gig RAM + 4 x 250gig in Raid 10 + Centos 5.3 64bit + Cpanel).
The machine is way overpowered for the traffic going to the site.
The server load is rarely above .10 and often closer to zero.
I'm getting periodic extreme slow downs. Web pages will take 30-60 seconds to load (or longer). SSH will timeout, or if I can connect, it will take seconds (sometimes 10-15 seconds) for key press to register in the SSH terminal. Pop3 times out, etc.
This might last for 15 minutes or 3-4 hours. Then, everything will start running like a champ again. Traceroutes to the server during the slow downs haven't shown a problem between the server and where I am testing from (have connected from multiple proxies and remote sites to eliminate my local internet connection).
I'm looking for any advice on how to trouble shoot this. Hardware? Software? Configuration issue?
It is definitely not a capacity/load issue. There have been no spikes in web traffic. The opposite, this is a very slow time for my site, which is why I moved to a new server in May.
I dont know much about what could be cuasing this so i come to you for advice, i am currently at wired tree on their VPS384 package with 348MB of ram and my site is really slow to load [url]sometimes it is so embaressing to show people i just dont bother, i am sure this is deferring visitors from my content how can i speed this up?
I can add more ram but it will push the price and if the price goes too high i might aswell move to a Hybrid with wiredtree.
My server gets 300 - 600 concurrent connections to http port 80, has a CPU load of 1 - 2%, has practically all RAM of 1 GB used, is running apache 2 and centos 5.
It tends to get slow and when I ban IPs that use many connections to my server (raping it), it becomes fast again. But soon after that new ******* users come which I again ban and the process repeats itself
I'm starting to think that maybe I just don't have enough RAM to handle them because it seems at least some of those users are legit. I don't however have even that much content that needs to be cached so I'm not sure what good RAM would do but perhaps apache just needs more.
My server has a small load (about 30% of it is being used) and it is still running very slow. When I reboot it runs fast for about 5-10 min, and then it is back to slow. I reported this to hivelocity and the responded with " The problem was one of your apache process was pegged out. Restarting apache resolved this issue. If you still have issues check top and run lsof on the process ID that is pegged out."
and after it continued "It will continur to happen until you isolate the source of the issue and stop it.
The load looked fine just now, so I am not seeing an issue.
What you can do is when it pegs out (simply restarting webserver will get it back up but not resolve) run the following command:
ps -aux
Look through the processes to see what is calling it."
Whn I run ps -aux i see a username on my server. i suspended that username but the problem is still happening.

I run a forum with a modest amount of traffic along with a content management system handling the other sections of the website. I'm pretty sure the forum isn't the problem though.
The server load for this machine is almost never above a 1. Right now as I type this the load is at 0.17, but it's unbearably slow! Taking up to 16 seconds to load a single page.
What could be causing this? I'm a server n00b. Is there a setting I should be doing to one of my servers configuration files to make it run faster?
My website gets 30-40,000 visitors a day and these problems always occur during peak hours. It would be easier to deal with this though if not for the fact that the server load is always so low. How is it possible for the site to get so slow while the server load is always so low?
I am currently hosting my website on one server with the specs:
2.8ghz Dual Quad-Core processor + 8 gigs of ram + two 500 hard drives with a 50 mbps unmetered bandwidth package.
My current problem lies in high server loads and very slow server performance throughout the day.
I am considering migrating over to The Planet onto server with the specs:
3.0ghz Dual Quad-Core + 18 gigs of ram + two 50gb hard drives with 2TB of monthly bandwidth transfer.
In an attempt to have great bandwidth pricing and server performance, I plan on downgrading my current server with my current host to a lowe-end server and keeping it only to host my VIDEO and MUSIC files with the 50mbps unmetered package. The Planet will then host my database and all other web related files on their new server.
Is this a good idea as an attempt to save money in bandwidth costs and eliminating my server lag issues?
I was offered a setup of a separate web and database server at my current host but from what I have read, no one touches the performance and reliability The Planet has to offer.
I just added a database server in private network and moved the database for Vbulletin Forum to this server.
But some how, the Forum is loading extremely slow compare to before ( when it was on the localhost). Also, Compare to another website on server (using local database) it is much slower.
One thing good is the load is lower
2 servers are connected via 10mbs private link, both servers are at Softlayer.
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.

Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.
I have a number of dedicated servers at different hosting companies, all with 100mbps burstable ports, using several versions of Windows (2003 or 2008, Standard or Enterprise).
I've tried setting up FTP servers (the one that is part of IIS) on 4 of them, to transfer files between the servers. But, I can't get a single transfer to go faster than about 10-12Mbps. If I upload multiple files, each will go at right around 10-12Mbps (so I can get, say, ~50Mbps if transferring 5 files simultaneously). I've tried passive FTP, and I've tried tweaking the TCP settings (TcpWindowSize, GlobalTcpWindowSize, Tcp1323Opts), and the results are the same.
I'm hosting about 6 private websites on my server, and some have problems.
My biggest website is a vb forum with 30.000 members and 1.5 million posts.
When i browse with firefox i see that vb forum loads fast, but phpads which is integrated on the top and footer loads very slow. When i browse with IE, it takes like 10 seconds before the whole site is loaded and sometimes IE even crashes.
When i try to login on another website / admin panel (oscommerce), i get a mysql gone away error, that means timeout. But why does it show that? I ran mysqlreport and can't find anything why it should display mysql gone away. # ./mysqlreport MySQL 5.0.15-standard uptime 3 19:36:47 Mon Feb 5 11:08:10 2007

I recently started hosting a large vBulletin forum (14,014 registered users... 30-60 online at a time) on one of my dedicated servers. When there's a lot of activity on the forums, things start getting really slow. There will be like 50 php-cgi processes running. Some users get blank pages, others get this message:
Notice: Undefined variable: errfile in [path]/forums/includes/functions_log_error.php on line 163
Specs of the server are: AMD Athlon 64 3000+ 160GB SATA HDD 2GB DDR2 RAM FreeBSD 6.2 (Hosted at AwkNet)
Could there be any Apache modifications I can make to increase performance, or anything else I could try?
I've been having a few issues with the control panel navigation is running slow even though I have heaps of resources available and free. The server is located locally and have no problems surfing websites attached to the same server.
When I login as admin, it can take 25 seconds to load into the first screen.

I have tried issuing a /etc/init.d/psa restart command and has made no difference.
Now-a-days server is having too much load due to http and in access logs we see following message : ======================================== 127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 - 127.0.0.1 - - [11/Oct/2008:01:40:03 -0700] "OPTIONS * HTTP/1.0" 200 - 127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 -=============================================
And due to this there is load on server. We are not able to understand why this is happening and how to stop this. So please suggest with some solution.
I am facing a strange issue with two RPG games sites that i am hosting on a 2GB ram server with softlayer, each of these sites was running on a 512MB VPS and they were doing fine but i decided to move them to better server so things run smoother when each has 50+ members online.
So the issue is when i have around 40 online members on each site, they start coughing up mysql errors, sometimes the sites just hang and stop loading, server load goes up to 3 or 4 but memory usage remains around 40%, I also notice that mysql uses the most of the CPU usage, around 75%
What i probably need is for someone to identify the cause of this, can it be an attack of some sort? or is it probably some code issues in the sites? do you recommend anyone that can have a look at this?
Today, without any change on the server side my single running website on my server started running low. After checking the running processes I realised I have these 8 processes running with high cpu load something that didn't had before.

frends now iam haveing dedicated server with pentium-4 and RAM is 2GB,my site online members is more than 100 members,now i feel slow in server,what i have add extra RAM or any chage in server
I noticed that there are huge pings to my server from time to time, example:
------------------ 64 bytes from HOSTNAME (server-IP): icmp_seq=0 ttl=60 time=2.93 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=1 ttl=60 time=2.70 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=2 ttl=60 time=1901 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=3 ttl=60 time=899 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=5 ttl=60 time=2.69 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=6 ttl=60 time=2.62 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=4 ttl=60 time=2132 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=8 ttl=60 time=2.57 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=7 ttl=60 time=1190 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=10 ttl=60 time=2.65 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=9 ttl=60 time=1048 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=12 ttl=60 time=2.74 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=11 ttl=60 time=1205 ms ------------------
First I thought that it is network related, but most strange for me was that I did not have any packets lose.
Then I tried to ping from my server to other hosts - situation was the same - some ping were good and some were huge (700ms, 800ms, even 2000ms)
I checked: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_max and it was 65536
Then I checked: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_count and it was ~1600 so normal.
I did not have such dropped information on all my other servers. Dropped counter for RX was constatnly increasing.
So I decided to restart all services on the server. After restarting network and ipaliases - problem disappeared. RX dropped counter is still rising, but I do not have any slowdowns on the server and pings are normal.
My question is - does anyone could have any idea what can casue my problem and how can I prevent this in the future?
i hosted 1 wesite ( forum script with no plugins )
when my traffic consuption reache to 25mbs the server running very slow for hours although the load avarage is very normal 1-2 Iowait 3% ram consumption 8-10Gb
my uplink port 1Gb and of course my DC said the connection is normal with no limitation
the server specs are good Quad procs 7200 ,16Gb ram ,15K SCSI speed
How can I prove to my web hosting company that the server is extremely slow and overloaded?
If I call support, they are saying that it is fine for them. But I've checked with different internet connections and it's slow.
I want to be moved to another server or get a partial refund or something. At this point my website is unusable during peak business hours.... and I get barley any traffic.
