Hi Pablo!
I suppose you mean the performance increase of one Pentium IV with
Hyperthreading compared to one Pentium IV without?
In reality (at least around here) turning on/off Hyperthreading isn't
increasing I/O performance in a way that is noticable. It will help if
you are doing heavy computations with the data at the same time, e.g. 3D
field simulations of data on XFS partitions. For normal fileserving
functionality Hyperthreading won't matter.
The point of multi-threading here is, that multi-cpu boxes can run
multiple threads at the same time and therefore use XFS parallel on more
than just one cpu.
If you are in need to get more performance, there is always the option
of dual or quad xeon/opteron boxes and better storage adapters and/or
RAID subsystems.
Cheers,
Frank...

Dear list, some days ago I've read in a XFS documents that some
objects like the Allocation Groups (AG) are multi-threaded. My
question is: is the performance improved when we use a multi-threading
processor like the Pentium IV? Please make a comparison between
Pentium and some other common processors.
Thank you very much.
