    Copy test times:
    2.6.0-test3-bk10 = ~ 2 minutes
    2.6.0-test3-bk10-final -- 2.6.0-test6-bk9 = ~ 4 minutes
    2.6.0-test6-bk10 -- 2.6.0-test9 = ~ 30 minutes (and more)

    Here's "time", "nfsstat" and "netstat -s" from the relevant kernels. I
    had shut down any excessive netservices and ran without X.
