No swap (default on that size EC2 instance)
             total       used       free     shared    buffers     cached
Mem:          3750       3731         19          0        274       2929
-/+ buffers/cache:        526       3224
Swap:            0          0          0

Caching heavily but not using so much RAM

Seems to slow down over a week or so so it might be a while...
