Only "near-instant" if your network isn't somehow acting up, sorry,
async is just the Right Thing here.

If you don't suppress dns resolution (-n) during routing table output 
for example, you potentially pause for a fair old while if there's 
problems with dns lookups (which could be caused by, oh, let's see, 
network routes being wrong...).  Much the same applies to arp tables
