I took a quick look at your packet trace and it appears that this client does all write FILESYNC. As such, setting vfs.nfsd.async=1 won't have any affect.
If you apply the attached patch, it should change the FILESYNC->UNSTABLE so that vfs.nfsd.async=1 will make a difference. Again, doing this does put data at risk when the server crashes. rick
