title: AppFabric Cache connection type and protocol
body: <p>Does the AppFabric cache API (local, not Azure) use WCF as its communications mechanism?  We are integrated AppFabric into a very high volume web application and seeing a ton of bottlenecks in some WCF calls.  The profiler makes it <em>seem</em> like these are coming from our cache library, but they are all very low level system calls, so we are curious..</p>
  
  <p>is appfabric cache accessed via a set of straight up set of TCP sockets connections? or are they some higher level protocols/designs that are layered on top of it?  Appfabric has a lot of benefits beyond other providers (like memcached), but if there protocol overhead is so much on a high-volume system, we are worried it may cause problems.</p>
  
  <p>thanks!</p>
