Hi, I have just committed r227809 to head/current which enables the new/default NFS server's use of shared vnode locks for Read, Readdir, Readlink, Getattr and Access.
Although it is hoped that this will improve performance for these operations when multiple ones are performed concurrently on the same file/vnode, I thought I should give a heads up. Why? Well it is conceivable that this may have negative issues that I haven't seen in testing along the lines of overloading a server, due to the lack of serialization of the above RPCs for the same file/vnode. If anyone encounters problems with their NFS server after upgrading to post-r227809, please email and let me know. rick _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
