Hi, all:
I want to compile the Dom0 based on Linux 3.17.4 kernel, and make sure all
of that the necessary config options for supporting Dom0 on official wiki ([1])
enabled. However, if I test the "network forwarding" performance for Dom0 using
traffic generator, I find that the performance is significant poor, especially
compare to SUSE 12 Dom0 (whose kernel is 3.12.28).
I know that SUSE has merged some additional patches to mainline kernel,
however, I am wondering if there are some kernel config options I have enabled
or missed influence the performance.
My config file for Dom0 is on [2], and the diff file compared to SUSE 12 is
on [3]. Could somebody can help to give some advice about it? Thanks.
