No problem, thanks for running your tests again..
What are your memory allocations? How much
of a bump do you get if you increase memory?
Currently, both dom0 and the vm have 128MB. I rebooted with dom0
having 512MB and VM with 256 MB. Here are the numbers:
dom0:
[ 5] 0.0-10.0 sec 987 MBytes 828 Mbits/sec
VM:
[ 5] 0.0-10.0 sec 938 MBytes 787 Mbits/sec
So getting slightly better. I haven't run these with SEDF though,
above are using BVT.
Yep, the bigger difference in Xen 3.0 is that it's
just more sensitive to memory - when I tested
earlier in the summer most of the difference
between dom0 and domU could be gained back by
350MB dom0 and 512MB domUs doing heavy network
traffic.
So you have:
128MB domU - 450 Mbits/sec
250MB domU - 787 Mbits/sec
Which is roughly the same amount off the linear that I
recall..
thanks,
Nivedita
