I tried with a bit simpler flows, like this:
ovs-ofctl add-flow br-int
hard_timeout=0,idle_timeout=0,priority=10,ip,cookie=0x$v,table=0,dl_vlan=$v,nw_src=9.16.$i.$j,actions=output:1
And while adding them one-by-one in my VM took 12 minutes (my dev VM has been
very slow recently), the runtime of the deletion was not noticeable, i.e., a
following flow dump returned right away. Deleting all 200 flows took maybe 2-3
seconds.
I’m trying again with the exact flow reported, but I’d be surprised if the
additional match fields would make a difference.
This on tip of master. I’ll have to try again with releases 2.4 and 2.5.
