Bug Description
If you build an image via the process documented here: https:/
and then mount a directory via NFS as described, a simple 'cp' of a 4MB file from the NFS directory to /tmp can take 10 minutes.
This is a known issue with user-mode networking in the model: ARM bug ID SDDKW-16090. Suggested workaround is to use TUN/TAP networking (I haven't tested personally whether that does indeed avoid the problem.)
Seen with Fast Models 7.0.
