Hello,
I''m using Xen 3.0.0. I wonder what the kernel options under
/proc/xen/net/eth0, rxbuf_{min,cur,max}, are.
At first, we saw quite a few tx-packet drops on dom0''s
vif1.0, where rxbuf_cur was always 8. After changing rxbuf_min to 256,
which is the same as rxbuf_max, we''ve never seen such drops.
I could only find a short commit message on the interface:
http://lists.xensource.com/archives/html/xen-changelog/2005-05/msg00033.html
>From the message, I guess they exist for configuring the buffer size
of domU''s virtual NICs. Are these options meant to be configured
manually for better performance? If so, how many bytes are rxbuf_cur
, say 8, going to consume?
Thanks,
Naoya
