CodeIgniter and APC Opcode caching

[eluser]Phil_B[/eluser]
Has anyone managed to get the opcode caching in APC working with CodeIgniter? The data storage works fine but I haven't noticed any improvement in page load times.

The apc.php overview page only lists the file path for the current controller as being cached. Whereas eAccelerator would list all of CI.

I've used eAccelerator successfully in the past and noticed huge performance boosts but it occasionally causes segmentation faults and crashes Apache.

Anyone have any experience with this?

Thanks
