Hi,
I'm doing researches on remus and have a question about its network buffering.
I use the code in the xen unstable tree.
I've run a guest and remus with network buffering(without --no-net),
using the default interval 200ms. Then I ping the guest on the 3rd
machine(other than primary and backup).
I found that the average delay is about 30~50 ms, but I think it
should be larger than 100ms.(due to network buffering, the output
packet could be held for 0~200ms)
Did I make anything wrong with the idea of network buffering? Or did I
make any mistake during the test?
Thanks,
--
