No performance degradation is expected.  hastd(8) maintains a map of
dirty extents. The map size is static, just more blocks are marked as
dirty during disconnect. It would only affect synchronization time
after the connection is restored.

You might consider setting the remote address to "none" (see
hast.conf(5)) to make hastd(1) even not try to connect to the
secondary.
