Is it known and/or expected that nfs:/// repos perform *much* worse than

As an example, I have two images that I started to update at the same
time. The repo is in SCA, the images are in BRM. I thought that NFS may
be the cause of the horrible performance so I hit ^C in one of them.
Then I started up a couple pkg.depotd processes for the on-nightly and
on-extra repos in SCA, changed the publisher settings on one of the
images to use http URIs, and restarted the operation (pkg change-variant
variant.debug.osnet=true).
Any idea what's behind this?
Hi Mike,
I don't know how far SCA labs are from BRM, but IPS makes a lot of tiny
FS operations instead of one big file transfer.
In case of traversing NFS across misconfigured routers or across vast
landscapes the stat() operations on NFS take very long time and as IPS
fires lots of such operations, this could explain horrible performance.
On the other hand if You have machine serving repo over NFS in the same
subnet and in the same LAN like machine being installed, NFS should have
better performance.
