CENTOS 6.5 Load Averages: 13.56 14.99 17.57

[cool_recep]

Hi guys.

We have a web site with daily 30K unique visitors. We are using Xenforo 1.3.2 and Wordpress 3.9.1.

We are having performance issues latley. Getting 408 Bad Request errors sometimes and slow loading.

Our Litespeed version is 4.0.1 (I don't know if our hosting provider is using a legal version, I would like to know )

Server Info:

CENTOS 6.5
PHP 5.4.28
MySQL 5.5.36-cll

Our hosting provider is trying to solve the problem but I don't think they are really experienced.

How can we solve the problem ? Is there someone or some trusted service we can get to have our server anaylzed? I have SSH/WHM access to my server and I can provide you all the other info. I just want to solve the problem.

Hi, you can PM the SSH/WHM access to me.
will check it a few times in next 24 hours

CMIIW, I thought it was because of bad habit of XenForo that using MySQL delayed_thread as their default pre-enabled option.

>> http://xenforo.com/community/threads/delayed-mysql-queries.44450/
>> http://google.com/#q=xenforo mysql delayed thread issue

It should be disabled forever from XenForo admin section.
Or at least make that terrible option disabled by default so user can choose to enable it latter.
Because mostly websites in this entire world using shared hosting, not all of them using dedicated server per site/forum.

@NiteWave , I have sent.
@DraCoola , It is already disabled.

We also had Revive Adserver but we have removed it.

replied in PM.

BTW, they told us that they have switched to nGinx because LSWS can not give response to requests and goes into sleep mode...

 

[mistwang]

version 4.0.1 is the old pirate version, hosting provider installed it for you? which provider?

 

[cool_recep]

Looks like it is already in the blacklist. We will ditch them.

 

[Michael]

That is probably for the best. They do not sound trustworthy.

We would be interested in knowing which provider is using nulled versions of our software. If you don't want to tell us, that is understandable, though.

Cheers,

Michael

 

[cool_recep]

I have told via PM.

 

[Michael]

Thank you very much. This is good to know.

Best of luck in looking for a solution. If you are looking for a trusted provider, we have a number of hosts listed in our partners section: http://www.litespeedtech.com/partners/hosting-partners

I'm sure you'll be able to find one in your area that meets your needs.

Cheers,

Michael

Thanks for the info. We will check those providers out.
