Hi,
   We are using ATS as reverse proxy. 
   In our use case most of the data is dynamic ( responses from the backend 
hosts ) and need not be cached for more than 5-10 mins.

   We currently configured it to have a disk cache size of 10 GB and we left 
the proxy.config.cache.ram_cache.size as -1. So that would give us a ram cache 
size of 10 MB.
    Here are my questions :

    1. Since the ram cache size is very small, does a TCP_HIT mean a disk 
access  ? ( this is a 16 GB node and lots of free memory, so I mostly buffer 
cache plays a 
        significant role )
    2. Given the nature of the data ( not required to cache for more than 10 
min ), any specific suggestions to make ATS more efficient ?
    3.  As far as I can understand from the documentation, it looks like only 
highly used objects will go to Ram Cache. According to that in our use case 
only few will
         it there. Any tweaks or change in algorithms to move as much as 
possible to Ram Cache.

    Please feel free to list out any specific suggestions for configuring YTS 
regarding this particular use case.
