Solution Verified - Updated -


  • Destroying network devices takes about 1 second on average each.

  • ifdowning the interfaces first somewhat alleviates the issue.

  • This is very noticable while using a script like following.

# set down a load of vlans


for ((a=10; a <= LIMIT ; a++))
  ip link delete eth0.${a}
