Hi!
We have freebsd10.3 gateway running in our private hyper-v cloud
(Windows Server 2012R2). Throughput of ipsec tunnel is very poor -
~3-5Mb/s sometimes slow down to few Kb/s with high cpu load and a lot of
interrupts.Downloading over ftp is about 30-40Mb/s. Disabling tso,rxcsum
and txcsum on hn interfaces do nothing.
