While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add

-s /path/to/memcache.socket
-a 0766

To /etc/memcached.conf and comment out the default connection port and IP, i.e.

-p 11211 
-l 127.0.0.1

However, when I restart memcached I get internal server errors on Drupal site.

I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak.

I appreciate your hints or possibly configs to to resolve this.
