Hi,
Too much time is spent on mmap() in rte_eal_init().
When running DPDK application with 35 1G huge pages, it takes about 12sec
in mapping().
Is there any way to reduce this time?
I guess it is okay to have that much time in first initialization. However,
if the application is restarted for some reason(for example, unexpected
exit) that long initialization can cause service continuity.
May the Fun with you.

Which DPDK version are you using? In DPDK16.04, below url did some optimization work.

I guess you are using an old DPDK.
You just need to upgrade :)

I am using 16.07. Is it already 'too old'? -_-;;;
Almost time is spent on mmap() not the memset()
