Apache Cpu Usage 200%

[cogeanumarius]

Hi to all,

I have started my web shop in a shared environment (ixwebhosting); I have received shortly after adding few hundred items a TOS ticket (Terms of Service Violation - Fair Use).

I have dedicated to purchase a virtual server (2xAthlon 1.8 GHz | 4GB RAM DDR2 | 2x320 HDD Mirror 5.4k rpm).

At the moment I have almost 3k products on my website but no more than 30 visits a day.

I usually receive alerts from the server that CPU is 100% and that Apache services are over the limit.

Here are some details that may help you to identify my issue:

PS version: 1.4.9.0 | Default theme | CCC - activated | Caching - Memcached - ON | PHP: 5.3.3 | MySQL: 5.1.67 | OS: CentOS release 6.3 (Final)

I would agree with a Presta Developer to login into my system SSH and (paid) advise about some settings that could improve the performance, this session will be recorded so that I could re do the settings in case of another migration.

Could the upgrade to the new version of Presta (1.5.3.1) fix my issue?

I am planning to migrate to an even more powerful server - dedicated: 8xOpteron 2.4 GHz | 32GB RAM DDR3 | 2x2000 HDD Mirror 7.2k rpm

I have the option of choosing the OS for the new server, these are my options: centos.org, debian.org, scientificlinux.org, ubuntu.com what do you recommend and the reason for that if possible. (Reason like, PHP extensions have better/stable integration in one of the distributions)

Thank you in advance for your advices/hints.

Are there any other details I should provide to you so that you could identify why there is so much load on my server?

Thank you in advance

Just a shot in the dark try with memcach off

 

from the sound of it you may not need it

you know, it may be something, I have deactivated "Memcached" and I am back on old "File System"

I will be monitoring it for the next few days and I will let all know if this was the problem.

Thank you for your advice ("the shot in the dark")

No, the problem is not there, even with "File System" I am still having several times a day overload alerts of the Apache CPU usage in Plesk 11 Control Panel, on Cent OS 6 x64.

I have started to add in the firewall rules all the search engines that are not Google, there are a lot from China and Russian ones.

But this will not solve my problem, when those queries from the search engines will be replaced by real people I will have the same issue.

Huge thanks in advance for your hints.

PS:

my shop have only one quantity on stock for each product, but almost 3k at the moment and 15k is the target for the next 2 years.

Any hint or tuning for this kind of shop? That does not have just 3 articles with thousands of items on stock.

Hi All,

 

same problem for me since 6 months...CPU usage always on 100% also if there are any visitor on my website...

I'm on a 1.4.9 too and in my shop there are no more than 300/400 items...

May be a bug of this version?

 

An advice will be very appreciated...

 

thanks

Deinstall all your extra (non-default) modules and try. PS 1.4.9. runs well also with 2.000 products and no accelerator or cache modules.
