hi paul
I was actually doing topology in lab out of curiosity. there was constant slowness in traffic from host to router ( host to 9k2 to router)
and on other hand it was working fine from 9k1 side path but after sometime issue of slowness started again in 9k1 side path as well
sorry i didn't have traffic logs as i was doing at my friends place and unfortunately he has deleted that lab

we can not see the picture to identify which one host? where did it connect?
what is the meaning of slowness? what is the IP address of the source, what is the destination you trying to reach?
is the nexus in vPC ? is this ever worked as expected, ? show us some config and details ? what you see logs on nexus switches ?

Hello,
is this a live network with a public eBGP connection, or a lab environment ?

hi,
lab environment

Hello
Considering you are performing mutual redistribution between a single router and dual 9k switches I am assuming that diagram you posted doesn't reflect the true nature of your network?
Can you elaborate on this slowness, Does it occur at specific times, is it effecting all users of just certain users/applications?
Have you performed any traffic captures, utilization checks, Looked for flapping interfaces, event logging, are you using quality of service, network translation, vpns etc...
Could you share a topology diagram?

show interface
check the MTU for both interface connect to Host and interface connect to Router.
fast then slow meaning there is drop in Queue the reason many be N9K receive packet large then it frag it to small to forward it to router.
