reply_queues - module parameter on the hpsa linux module

Hi!

 

"modinfo hpsa" has this parameter:

 

parm: reply_queues:Specify desired number of reply queues. 1-16, default is 4, not to exceed number of online CPUs. (int)

 

Has anybody tried to experiment with this number to see if one can get more performance?

Google has pretty much 0 results except for the release notes.

Getting a new machines that needs to be benchmarked, but this is months away.
Bit excited to see if this can make a real difference :)
