comment Should I set rto_min for a route inside data center?
@Janning max latency is proportional to cumulative size of all buffers along the way. Speed of light is negligible in your case.

comment Should I set rto_min for a route inside data center?
I guess rto_min should be set not with regard to current latency, but w.r.t. sizes of buffers along the way and bandwidth. For example in presence of traffic bursts switch/router can hold frame/packet for couple of milliseconds.
