Hi!
I'm running 3 websites on the same server. All of them run on PHP 5.4. We follow the recomendations for setup IIS and PHP: http://bit.ly/S87EC9
In the last days we are experiencing a couple of problems on one of our websites. That particular website is a very visited one (we have a media of 120 concurrent users). And the problem is that takes a lot of time the execution. Sometimes, it makes the entire machine slow, and we have to restart the machine via remote KVM to get control again.
We tarted to disable extensions. Currently we are using only 3 extensions with PHP 5.4.0 nts (Installed via WPI):
- php_curl.dll
- php_soap.dll
- php_sqlsvr_54_nts.dll
The website connects to a SQL Server that run on another server in the same network. What we notice is that when more people navigate trough the website, more slow it becomes.
When we connect to the server we notice a moderated memory consumption and the processor use is below 5% always. (We are running on a dual processor machine with 8 cores each processor and 12GB RAM). And when we check the SQL Server we get a similar picture. Moderated memory consumption and.low processor use.
On a first sight, we think this problem was caused by an old PHP version (we were using 5.2.17). So, we update the code and make the website work with the version 5.4, but we get the same problem here.
Do you have any advice? Anyone has the same problem?
Do anyone knows an IIS specialist in Argentina that could help us?
Regards
Jonatan
