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

Subject: [dpdk-users] Too much time in mmap()

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.
