Hi,
I have a small Drupal commerce site on a VPS Dual Intel Xeon processors with 16-24 CPU Cores, 32GB RAM, Raid 10 Drives with 15K SAS drives (SSD energised) with 1536MB memory limit.
I have allocated my commerce site with a 512MB memory for the time being as that seems to be more than it needs.

For anonymous users I use Boost right now combined with Ajax blocks (for shopping cart) and thats working quite nicely but, that was the setup I used out of necessity on shared hosting but now that I migrated to a VPS I am looking to boost it up a bit.

Does it make sense to use APC for logged in/backend users and Boost for anonymous?

If Yes, can anyone please tell me what would I add to settings.php in that case as read me lists steps 2a and 2b but it doesn't really explain use case scenario in layman's terms?

Thanks in advance
