Load Balancers?
Aug 19, 2007I'm just curious, how many around here use load balancers in front of their webservers, and what kind of traffic do you push with them? (What kind of load balancer as well) Any other specifics would be nice as well.
Also, do you have failover for your load bal?

Jul 1, 2009We are looking for some experiences and suggestions for a good mid-level hardware load balancing solution for http traffic.
We've started looking at the Coyote Point E350GX, but would like some other suggestions from those of you that have direct experience with this or other platforms.
Two requirements are that the devices *must* support some type of HA / failover configuration, and be able to handle a minimum of 750+ Mbps of traffic.
Anyone Using Zeus Load Balancers?
Aug 6, 2009I was thinking of using LVM, but started looking at some other solutions. I would like to use a virtual appliance if possible as I'm almost tapped on power in my colo space.
Has anyone used the zeus load balancing product? Yeah or Nah?
Hardware Load Balancers Obsolete?
Nov 10, 2006I just purchased a hardware load balancer for redundency. I just wanted to ask, with the introduction of "Grid" AppLogic OS, will hardware load balancers now become obsolete? Especially if they cost about $25k and are still a single point of failure? Will this new software have an impact on the necessity for dual + quad cpu servers?

Dec 20, 2007I'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.
Copy these into the browser:

And when i run cat /proc/user_beancounters:

This line is particularly scary:

Load Testing :: Server Load Testers ( Commercial )?
May 6, 2008Anyone 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.
Some Sites Load Slow, Some Sites Load Fine, Server Load Is Fine
Aug 12, 2008I'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?
How To Check Load Via Ssh And Check Files Causing Load
Jul 1, 2009I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts
VPS Load
Mar 16, 2009I just got a futurehosting VPS recently and something is puzzling me. Is it normal that an idle CPanel virtuozzo VPS that has no sites on it should display "top" loads of between 1 and 4 regularly? I've been watching the load for a bit now and it keeps jumping between 0-4. When it goes 1 or above, the WHM panel becomes really slow, timing out... They seem to use a beast 8 core machine, so it would take some activity to cause even a 1 load..
I do not have much knowledge about VPS hosting, on a dedicated I would expect the loads to stay 0-0.2 at this point... Is the 1-4 load showing the result of heavy usage by other VPS users on the node? There is absolutely nothing that could cause a load in my vps as far as I see... Is this perfectly normal on any VPS?
CPU Load: 259.33/166.35/119.93
Jul 14, 2009You think this is funny? Not at all.
I'm on LON03 server and I recive yesterday from Future Hosting this advise about hight load.
I got then 1 month ago, and the solution was *JUST* to remove a phpBB website with 80+ users.
I do not believe that the VPS could get this kind of loads.
Funny is that the VPS was "monitored" by them at the same time. They say the load spikes out for times to times in a matter of seconds.
This load is taken from the Parallels Infrastructure Panel or even the Node Panel, not from the VSP itself. Even when I'm logged in.
I've been a client for 6 month, and 2 of the last 3 constantly getting CPU hight usage. Strange is, that I come from a 512mb/25gb PowerVPS server to a 1GB/30GB server, with the *SAME* sites.
Anyway, the prupose of this topic is to:
- check if anyone had this problem (problem is: beeing sure that this load is IMPOSSIBLE to be created from yout service)
- recommend a decent VPS provider besides Future Hosting and PowerVPS.

Load Balancing
Jun 21, 2007I want to have a fail over for my server. I was told that load balancing is the way to go.
Could anyone give me some instructions of what I would require. My primary server contains Cpanel.
Load Balancing ...
Apr 8, 2008the loads on my server is VERY HIGH and it needs to be upgraded fast.
I really have no clue as what to do... and i do not know any expert other than you people here - to help me out and put me on the right track.
i was thinking of
1) Getting a server with better CPU and more RAM
2) Load Balancing
However I know nothing of load balancing (other than how to spell it correctly )
1) Which of the above two options should i choose?
2) what are the extra costs in load balancing?
3) what should i know about load balancing before deciding?
4) How does load balancing work? I know there are two server - like one for database and one as webserver... but how does this work together?
5) what config should i be looking at in the two servers?
I'll stop here else i can go on and on and on...
I am giving the details of my server and service below, in case you guys need it.
Load Balancing / HA
Sep 18, 2007We host a large number of small websites and are looking for high-availability and the ability to do maintenance on our application servers, so I'm looking for a load balancing solution. At this point, I'm considering Zeus ZXTM LB software, the Coyote Point e350si, and potentially an F5 1500 LTM.
The F5 solution is a total budget buster, and the Coyote Point UI is rough around the edges, but I've used them and they are reliable. Zeus looks like a winner with a great UI, but I haven't heard much about their reliability.
Bandwidth requirements are low at this point, so this is mostly about reliability and ease of configuration of a moderately complex set of services.
Any opinions on these vendors, or alternates I should consider?
CPU Load Balancing
Oct 23, 2007I run a GSP (Game Server Provider) and i just baught 2 new octi xeon servers(Intel 5320)
i am having a problem with the load balancing, it dosen't balance de cpu usage on all cores but only on one, and it gets at about 80-85% and 3%CPU usage on the other one.
Load Balancing?
Jun 18, 2007I was currious as to some suggestions you guys may have for setting up a load balanced website...
I would preffer it to be software based and free as I am just using this for some testing purposes.
Load Balancing Over WAN?
Jul 11, 2008I'm looking at load balancing a group of servers located at different data centers.
How feasible is this? Which options/solutions should I take a look at?
I would like to route using some sort of IP tunneling or similar so that the user doesn't see ww1.domain.com etc.
I will be distributing the load of the static/dynamic web pages, no database clustering.
I would prefer something a bit more intuitive than round robin. Perhaps directing incoming traffic based on existing server load etc.
Most of the load balancing solutions I've looked at assume all your servers are on the same local network.

High VPS Load
Jun 24, 2009My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)
