Disable offloads on the sky hardware and see what happens? ethtool -K gro off tso off gso off your_device
How old is the OS on that hardware - offloads have always been tricksy. as to why you might be seeing it more with cake, with this stuff on, you are not necessarily checking every packet for checksums, and flows are "finer" - more mixed up packets. capturing these events with tcpdump at various points on the path might help. Still, these are the kinds of baseline deployment issues that block progress elsewhere. The whole first stage of the rocket has to succeed in order to test the second. Doesn't matter how good your second stage is, if you RUD the first. Good digging! _______________________________________________ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake
