Reducing TCP retransmit timeout?

Cloud networks are lossy and low latency, reducing TCP_RTO_MIN and TCP_DELACK_MIN looks like a good idea, but it looks as if this needs a linux kernel recompile. Anyone else looked at this?
Here is a relevant paper “Safe and Effective Fine-grained TCP Retransmissions for Datacenter Communication“

    Yeah TCP_RTO_MIN does require a recompile ... without giving any details on my project ... this is a good area to explore.

    Cheers,
