    Server Load

    Hi

    I have a reseller account through a shared server. My clients sites and my site time out often, I have reported this to my provider and get alot of excusses. Tell me if this is normal.

    Should I start looking for another Provider, I think this server is way over sold.

    yes, the server loads are high, but doesnt it depend on what kind of machine it is being hosted on?

    or is 20, 10, and 5 just to high no matter what?

    That's extremely high. They've probably got a client running some resource-intensive scripts or something of that nature. If your host doesn't do anything about it, I'd get out of there as soon as possible.

    I just got an email for the support desk telling me (the load seems to be quite ok when compared to previous days when it spiked up to 15+ )

    This is in the last hour

    10 is still very very very high.. I mean it is peaks out once in a while that is one thing but I have a feeling they are loading like 1000 sites on your server, Can you see how many sites are on that server?

    Hi No I can't see how many sites are on the server, bandmin is password protected.

    Well it seams your right, My Host sent me an email regarding this and offered to move me to another server.

    I think I will take him up on the offer, since I only have a couple of accounts, and one script that need to be changed in regards to ssl.

    I want to thank all of you for your input.

    My host has treated good so far, there tech support has been good. I just wanted to give them the benifit of the dout the same way I would expect my clients to give me the benifit of the dout when things of this nature come up.

    Thanks

    It depends if the load is consistent or if it's just high for a few seconds. I don't like to see my load consistently over 1.0 on my machines.

    A load of .48 is good. Anything above 1.5 isn't good on a single processor machine. A load of 5-10 on a dual processor machine isn't good.

    Whos your provider?

  13. #13
    I think it's a juggling act sometimes, on one hand you the heavy hitter( The very busy site) it's a popular site that continues to grow. Then you have the static sites that are lucky to get a couple hundreds hits a month. Now if one of the static sites starts to get busy and get's a programer to start adding some fuctionality to there site then your going to see an increase in loads and someone is going to have to move.


    Now we have Cpanel that gives the novice user the ablity to install scripts at the click of a mouse. I think this is going to be a
    problem down the road for small resellers like myself.

    Don't get me wrong I love Cpanel and that ablity to install scripts but how many bulletin boards or chat scripts can you put on a server before it starts to slow to a crawl.

    I am new to reselling and My host has held my hand through the learning process.

    That's my 2 cents take for what it's worth.

    Thanks for all the input,

    Still Learning

    who is your provider? I'm currently with a provider that I like very much, but I'm starting to notice some high server load, a little slowness, etc..etc.... The server and the CPanel stats you posted about look very familiar....

    That is just too high. I have recently had similar problems which was resolved by a kernel rebuild etc.

    .5 - 1 is OK but going to 10 - 20 on a single CPU is no good - they should maybe think about moving the database or the mailserver to a different machine so as to reduce the load. This way it will not affect sites so much who do not use so many resources.

  17. #17
    Basically as it was explained to me a server load of 1 means that one means that the server CPU is performing at full capacity; that is each time a cycle of instructions is processed another is immediately entered into the CPU. If you have a load of 10 that means there are 10 instructions waiting each time the CPU is available therefore the server slows. Anything below 1 and the CPU is not used to full capacity.

    Spikes above 1 are okay and usually occur on servers when people are running stats, zipping up their sites for download or are running intensive scripts. You just don't want a constant high server load.

    This is an area in which the hosts should monitor. How many sites on a server really doesn't matter these days; it what those sites are doing on the server.

    Load doesn't have anything directly to do with overselling. You can have a single script run your loads up that high. Of course, you might have a thousand small accounts all running to get that high load too, but it could as easily be a single account. The question I'd ask is if this is a consistant thing that slows the responsiveness of your website. I can't imagine it's a good thing, but it's up to you to figure out what you'll tolerate.

    One of my hosts tends to fluctuate between 0.5 and 90 with what seems to be an avg around 5-8 here lately. I haven't really noticed a performance problem until it hit 70+. Is there some way to find what would be using the resources?

    They need to find out who is causing the load and suspend them. Often it is one or two threads on the cpu. They can see which user own that thread if they want to.

    CPU's will spike at various times but sustained utilisation like that is very poor.

    Interesting, I just saw one of those spikes up to 162. It went down a few minutes later just when I picked up the phone to call my host. Is there a way to see the user if their scripts aren't suexed? From what I can see from SSH, most processes seem to be run by 'nobody' and a few run by some random number.
