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 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.

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'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.

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'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'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.
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.

Having this issue with a robot Twiceler recently on my server. It is running around 12 queries for pages per minute and those page request are sql intensive.
The issue is that it runs from 3 different IP and are pretty aggressive in making request 2 requests within 2 seconds.
Anyone have any experience with this spider? What does it do and who runs it? Or it is just another script that anyone can download?
I am thinking of banning the IPs and the spider all together if the spidering serve no purpose.
I have a website currently hosted on a Godaddy shared hosting plan.
Visitors to the site have reported getting "Service Unavailable" messages at times. When I talked to Godaddy about this, they say I am exceeding the limits they put on simultaneous page requests (or something to that effect). For my plan this limit is set at 100.
I upgraded to their highest shared hosting plan, and this limit now goes up to 150 simultaneous requests. This will probably solve the problem for a while, but I think the site will grow enough to have a problem at 150, and I need to figure out what to do when this happens.
The site currently gets about 4800 visitors a day, and uses around 5 gb of bandwidth per day. The site is: BuildItSolar dot com
Questions:
- Am I likely to find a shared hosting plan that is better on this limit than Godaddy?
- Is the site getting large enough that some form of virtual dedicated server or dedicated server is going to be necessary?
- Godaddy offers virtual dedicated servers, and dedicated servers. I wonder what I would need to go to solve the problem, and provide some capacity margin for growth?
Is the lowest level of virtual dedicated server really going to provide any better performance than the shared hosting plan I have now? Godaddy was not very helpful on answering these questions.
- Any recommendations for virtual dedicated server or dedicated server outfits that are good?
Sorry about so many questions on my first post. Wish I knew more about this whole hosting thing.
I run a centos 6 plesk 12 server with around 7 domains.All runs perfect untill a 3 hours ago. The server was offline.After reboot plesk starts up without a problem but the sites keep offline. While httpd and mysqld and psa runs perfect.Also cannot find error messages in the messages, error_log or anything. How to proceed debugging?
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've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time. That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?
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
