Hi Anad, Happy to hear that it worked for you.
Regarding the performance: this is strange to hear. Are you sure that you are running DPDK the same way in both cases (same parameters, same /proc/cmdline, etc)?

But still I face the same packet drop issue. Any guess, what causing problem?

In order to be able to do so, keep the GRUB_CMDLINE_LINUX as what you had in init level 5, and assuming you are using one of the popular distros (like Fedora or recent Ubuntus), which runs systemd, the recommended way to what you call "disable the gui" is by a systemd command called systemctl. So, when the gui mode is enabled, you will get: systemctl get-default graphical.target And to disable the gui you can run: sudo systemctl enable multi-user.target --force sudo systemctl set-default multi-user.target After boot, both in run level 3 and in run level 5, you will be able to verify that the kernel command line is as expected with: cat /proc/cmdline Regards, Rami Rosen -----Original Message----- From: users [mailto:users-boun...@dpdk.org<mailto:users-boun...@dpdk.org>] On Behalf Of Anand Prasad Sent: Tuesday, April 10, 2018 15:12 To: users@dpdk.org<mailto:users@dpdk.org> Subject: [dpdk-users] Running DPDK application in Linux init level 3 Hi DPDK Team, I am trying to run DPDK application in Linux with init level 3 (no gui) and I am observing continuous packet drops on Rx side. But, If I boot Linux in init level 5 (GUI), then I dont see drops. I have provided linux command line arguments (for isolating the cpu cores and hugepates etc in "GRUB_CMDLINE_LINUX_DEFAULT" variable, and with those it's working fine in init level 5. But, not sureif these configuration are applicable when I boot in Init level 3? To boot in init level 3, I am setting GRUB_CMDLINE_LINUX="3" , is it correct? If not please suggest what is theother method. Thanks in advance.Anand
