I have been doing some experiments with XFS on my "hot new desktop system," and 
I have turned up an interesting bit of info. (Note: My system is an AMD64 X2 
2.5GHz running Linux.)

When I mount an XFS volume (thus loading the xfs kernel module), the kernel 
spawns two CPU-bound threads for "xfslogd" and "xfsdatad". However, it appears 
that only one of each of these kernel processes is getting any load, as 
indicated by "ps ax":

 3700 ?        S<     0:00 [xfslogd/0]
 3701 ?        S<     0:19 [xfslogd/1]
 3702 ?        S<     0:00 [xfsdatad/0]
 3703 ?        D<     0:05 [xfsdatad/1]

For each of these kernel threads, only those on CPU #2 are actually pulling 
notable load. Why is this?

I understand that I may have overlooked some critical tidbit of info in the man 
pages, or perhaps I have not yet found something online that could explain a 
default limitation. If so, I would very much enjoy new information about using 
XFS on a desktop system.

TYIA for your answer(s).
