Recommendations for kernel config
...hedulers and
so forth for optimum performance.
There are a few areas that raise questions in my mind and I wonder if
anyone has any opinions/comments on which settings are most suitable for
use with asterisk:
SLAB Allocator (SLAB or SLUB?)
Tickless System (?)
Preemption model (?)
IO Scheduler (Anticipatory, Deadline or CFQ?)
Flat or Sparse Memory (?)
Timer Frequency (100Hz .. 1000hz)
Cheers
Alan

Xen 3.0.3 disk i/o
Hello,
I''ve seen from time to time where a domU using heavy disk I/O can slow down
an entire server (including all other domU''s and dom0). Is there a way to
schedule or limit this in Xen 3.0.3?
Thank you,
Brian
