At Mellanox we're also seeing that = NFS mounted shares are extremely slow building even a single module. = Maybe the output from the find can be cached in a file somehow? Committed the fix within a day of this message (so three weeks ago): https://svnweb.freebsd.org/base?view=3Drevision&revision=3D285124 Is it not working? this is the first negative report I=E2=80=99ve heard = since Adrian and Roger posted. I spiked the test-build with a find that = recorded every time it ran. W/o the fix, it runs a lot. With the fix it = ran once. Is this not the case still?
