APC not caching many files
- by tetranz
Hello
I have a Drupal site running on a VPS at Linode with PHP 5.2.10 and APC 3.1.6.
It never caches more than about 25 files and barely uses any of its available memory. Drupal has hundreds of php files. I have another server where APC seems to work well and does indeed cache hundreds of files. The only difference with that site is that it runs Ubuntu 10.04 and php 5.3.2. The config settings are the same.
What could be wrong? I'll paste the config from apc.php below. This is after hitting multiple parts of Drupal.
Thanks
