"show ip cache flow" is slow and stalls

hank

Ever since we switched to ASR1004 running XE15.1(2)S1, we have seen that the output of "show ip cache flow" stalls

and is super slow to complete.  We have a few interfaces with "ip flow ingress" defined. What can be causing this

slowness?  Any recommendations of commands to speed up the output?

Thanks!

I think that slowness i you are seeing with command show ip cache flow are caused by a huge amount of traffic comming to ingress interface , the protocol "netflow" is a process with low priority in comparaison with switching packets (L2 and L3)

so theses main processes (routing, swittching , cef) will be prioritize rather than netflow or nbar.
