I used SilverStripe 2.4 to build a backend for managing data for a website that is not based on SilverStripe.
Currently I use the REST API of SilverStripe to retrieve data from the backend.
But this is a high traffic website and things get more and more slow because of the number of HTTP requests made through the REST API.
I know it is more a server issue, but to speed things up, is there a way to talk to SilverStripe directly though PHP? Something that does not hit apache for every single API call.
Currently I only use GET method of the RESTful server to retreive data and call some methods to e.g. resize images.
It would be great to hear your experience or if you could point me into the right direction.
UPDATE: I forgot to mention that both sites are running on the same server (SilverStripe in an subdir).
