amd64 shutdown during USB rsync

2019-02-02 Thread Mark Carroll
Hello. I'm trying out NetBSD 8.0 (GENERIC) #0 on an old Intel Broadwell NUC. I have a couple of USB3 portable HDDs plugged into it, each with an encrypted FFS filesystem mounted via cgd. Doing an rsync from one to the other it gets around 800GB through but can't finish it off: each time it does a

Hello, I have a NetBSD serving FFSv2 filesystems to various Windows nodes via Samba. The network efficiency seems to me underpar. There is very probably Samba tuning involved. Windows tuning too. But a question arised to me about miscellaneous speeds of ethernet cards connecting to a card on
