I'm trying to swap an IP alias from one network card to another, and so I'm flushing the route cache. To measure how long this takes, I have "route -C" running in one window with a timestamp (seconds and microseconds) after each iteration. I then issue the "ip route flush cache" command with a timestamp after it in another window. This returns right away. However, from the time the command is issued until the cache is actually cleared is two whole seconds. I would have expected it to be essentially instantaneous. Does anyone know why this is taking so long and maybe how I could speed it up?
