Based on the Nvidia Grace Performance Tuning Guide, implement optimizations.

Optimizations:

  1. MTU to 9216 on interfaces
  2. Disable irqbalance service: systemctl disable irqbalance
  3. IOMMU 
    vim  /etc/default/grub.d/iommu_passthrough.cfg 
GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX iommu.passthrough=0 init_on_alloc=0"
update-grub
reboot
  4. NUMA balancing setting (echo "kernel.numa_balancing = 0" >> /etc/sysctl.conf)
  5. Set swap file size of 24GB - 48GB
  6. cpupower frequency-set -g performance

1,2, & 4 have been completed in 4589e2.

Need to test updating the cmdline and power frequency.
