Hi Shirley,
>Running java based applications on the same server with a dpdk based
application has an impact on the dpdk performance.
Probably since the JVM generates kernel based processes. I
This is true, but as far as I know, using isolcpus should prevent these
processes to run on the isolated cores.
Just to be on the safe side: did you make sure with cat /proc/cmdline on
the kernel you are actually running indeed
has the "isolcpus=1-5" you added in grub ? sometimes, especially in multi
OS hosts, adding entries in /etc/default/grub and running grub2-mkconfig is
not enough, if you boot from a different partition.
Regards,
Rami Rosen
