Xen devel - Sep 2011 - A problem/suggestion about network ring buffer

Hi

Recently some observation suggests that Xen''s one-page sized ring
buffer is
not suitable for 10GB Networking environment. Sending packet at that high
rate may cause the ring to overflow. So I''m now wondering that should
we
provide some mechanism in future versions of Xen to make the ring size
configurable (such as passing the number of ring pages through xenbus)？

Paul,

Were there any plans to address ring buffer size as part of the
netchannel2 work?
