I'm trying to find some better docs on getting throughput up on a high
latency link. I have multiple machines, and the local link runs at
~7500kB/s all the time. The remote runs about half that on the same
hardware. The docs I googled are all over five years old, and may be
incomplete for current kernels.
I increased memory sizes in net/core/*mem* and rmem-* wmem_* in ipv4, as
well as changing the thp_adv_win_scale. Looking at the traces, it
appears that the number of packets in flight are increasing, but the
throughput is still low.
Any pointers, examples of working changes, or thoughts would be helpful.
