971	optimization: instrument pswarp to determing the ammount of wall clock time spent in I/O	jhoblitt	Paul Price	It would be nice to empirically figure out exactly that the interaction is between disk I/O caused by NFS, the Linux block I/O schedulers, and the Areca RAID controllers are.  It is possible that the Areca hardware deals with I/O requests in an sophisticated enough manner that we are actually hurting overall I/O performance by trying to do any cleaver block I/O scheduling.	enhancement	closed	high		pswarp	unspecified	minor	invalid
