Hello,
I'm using FreeBSD stable/12. Creating/destroying bulk vlan interfaces takes
too long to finish. Running parallel doesn't matter.
Is there any fast way to create 100 vlan interfaces?
seq 1 100 | /usr/bin/time xargs -t -n 1 -I % ifconfig em1.% create
...
ifconfig em1.99 create
ifconfig em1.100 create
14.78 real 0.03 user 1.19 sys
with 4 parallel workers:
seq 1 100 | /usr/bin/time xargs -t -P4 -n 1 -I % ifconfig em1.% create
...
ifconfig em1.99 create
ifconfig em1.100 create
14.46 real 0.03 user 1.20 sys
destroying:
ifconfig -g vlan | /usr/bin/time xargs -t -n 1 -I % ifconfig % destroy
...
ifconfig em1.98 destroy
ifconfig em1.100 destroy
21.89 real 0.03 user 1.64 sys
Any suggestions?
