hi, i'm having some performance issues on my server but i'm not sure what's causing it or how to fix it.
when the server loads and memory usage are within 'happy' levels, and the apache status is regular, one of my sites is lagging very slowly, while all of the others are loading fast as normal. the pages themselves aren't loading slow, but they are taking an abnormal amount of time to retrieve (i.e., the page will be completely blank for a few seconds, before any data is transferred, and then once it connects it will load quickly).
any ideas as to what can cause this? i'm running apache 1.3 on a cpanel centos 3.4 box, i've got mod_security, mod_dosevasive, and apf running, but disabling those didn't help the problem. any help?
but. if this really happen only one domain this look strange for me. only thing tat may be you have problem with dns resolving. what happen if you try connect to this site without domain (http://youip/~username ?

Could you please have a check on the code. Though I am not sure if that is in your case, but I had seen such cases in which the exact issue was php virus attachments to the code. Please have a check anywhere in the code of any attachments. It may perhaps look like the zend extensions.
No .. i mean in your index page of the site you are having the issue and the pages you include using the include functons. I this is only a possible cause. We can say exactly what the issue is with out having a fdetailed look into it.
Create a test html page in your website and try to access it. If it does not seem to work, the problem is not related to PHP, but a website wide. Also check .htaccess file to make sure that there is no redirection is set which causes the low speed. have a look at the error logs to see if there is any logs related to the particular website.
Btw, do you have the same issue for your sudomains(if you have any) also?
hmm..yours is a strange issue. If there is any attack exists to your website, it should affect all other websites hosted in the same server since it makes the port 80 busy all the time. but this is not in your case. I don't think I can say anything more regarding this issue as it needs access to the server
Just try to access the site from the server itself and see if there is any change. It may give you a better picture about this issue.
