Welcome to the second half of 2020 after a brief holiday hiatus from The Four Hundred and therefore the IBM i PTF Guide.

The HIPER is IJ25390, and it is for slow TCP performance with the Virtual Ethernet adapter and large send. Here is some more on that LSO – short for large send offload – and specifically a link that explains it better than we did two weeks ago, plus another link to a …
