I've read about APC that it speeds up multiple php file sites. So I have this particular project in PHP with many files and i discover that require\_once and parsing only class definitions (without executing them) takes most time.

So I've installed APC on my CentOS 5 server. I moved apc.php to my webserver and it displays 

```none
Hits: 1 (50.0%)
Misses: 1 (50.0%)

Cached Files    1 (281.1 KBytes)

```

And I can go to website and change subpages and so on, and apc.php still shows only one cached file ??

And in phpinfo() it shows that:

> 
> APC Support enabled
> 
> 
> 

I don't know what to do. Is APC working (like phpinfo() sais) or is it not? Only one cached file is not much after browsing some pages on my website.

And further more how to diagnose errors and make sure that APC works? I've browsed

> 
> apc.mmap\_file\_mask /tmp/apc.QnLqNf /tmp/apc.QnLqNf
> 
> 
> 

Directory /tmp but I don't have any files of apc there like it's stated in phpinfo should occur.

Please help me check if APC is working and if not, what can be a problem.
