Not as significant as the pending DAT patchset, but still a -15.94% OGM overhead saving on our ~200 nodes network. The theoretical upper limit would have been 23.5% with a raw OGM message size of 68 bytes reduced to 52 bytes. The measured 15.94% also includes +14 bytes ethernet frame size and batman-adv aggregation though. The more OGMs are aggregated, the closer you'd get to a 23.5% saving. $ capinfos ogmv1-1week-before.cap: ...
