High performance

I want to clarify how php and apache work together. If I had an 10GB RAM app server with apache and php, and MySQL on its own dedicated server, how do I determine the maxclients. If I understand correctly, if I set the max_memory in the php.ini to say 128M, and maxclients = 200, there is the potential to try and consume 25GB of memory. Plus, if Apache uses 20M per process, that's another 4GB, so the potential is around 29GB. I know that it is unlikely that all php scripts would use all 128M, so I'm wondering what is a good rule of thumb to start with.

All I'm really seeing online are reviews by affiliates, so I thought I'd ask for more unbiased opinions.

Any of you had any experience using CloudCache's CDN? I was sent a coupon and it would be very cost effective for me to use them, but I'm not sure if the service is good.

Hi,

When I enable any Drupal modules on the site it through following error message and site is not accessible after that:

“The website encountered an unexpected error. Please try again later”.

Following errors I found after hitting button and then look on the watchdog table.

1)Message Notice: Use of undefined constant user_access - assumed 'user_access' in field_indexer_menu() (line 16 of /home/drupal/ww/sites/all/modules/contrib/xmlsitemap/field_indexer/field_indexer.module).

Hi,

Can somebody please check my Mysql config and give some advise?
I use Percona 5.5 server. My server has a 16gb ram.

Hello, my problem is that :

I want to do a single site but with approximatively 300 modules on it. My site has to do a lot of sites.
With this amount of modules we can't forget performance (and I don't want).
So, my idea was that:
In place of a big site, i create a lot of small sites communicating between them.

My ideas are:
To create these sites as subdirectories of the main site to avoid the login problems.
Of course, to share the users tables among these sites.
To use the module front to make redirects to the login page of the main site.

when you call a telephone service and all operators are busy then you get a message to wait in line or call again latter, can we implement this for php as well?

correct me if i am wrong but when request for php application reaches max execution time then the script dies and never respond to the browser
so while the browser shows continues loading state, the server side may have already died long ago and not really continuing processing
but site user will continue to press reload page or waiting unnecessarily long time for page to load.

I've tried to post this here a couple of times, where I suspect it's a better fit, but it gets refused every time:

"Your submission has triggered the spam filter and will not be accepted."

So, posted in Forums (https://drupal.org/node/1571680).

Still hoping someone here can take a look.

I've been trying out several VCL files across the web but my problem seems to be a bit different. I have several websites (Rails + PHP) running on my server on Nginx + PHP-FDM on port 80 and I need to setup Varnish for one of my Drupal websites only so I obviously cannot change the port 80 to be used by Varnish as all the other sites will go down as well.
Any Ideas what my VCL file should look like in this case? (PHP-FDM is running on port 9000)
