ralight · ralight · commit c89536cd78d4 · 2013-07-20T09:14:25.000+01:00
Low keepalive values may be important in some applications, but this is something that should be decided after some thought. A minute keepalive should be acceptable in most cases, so is more appropriate as a default than a low value.
