Re: Benchmarks: Linux Kernel RAID vs a Hardware RAID setup

Richard,

Are you sure that the patch you reference below is actually in 2.6.26? 
I checked the CHANGELOG and couldn't find anything about get priority 
stripe in there (maybe its called something else now)?

Thanks
-Thomas

I can't comment on the above, but looking at this: 
 

http://marc.info/?l=linux-raid&m=120668318422034&w=2 ;
 

with the 2.6.26 release, bumping up the stripe cache should no longer 
be
necessary.
