Node-red on two Pis same network- slow comms

I configured two Rev Pis with different IP addresses. both are on the same network. When i ssh into either of the Pis or open the node page, they get really slow. A letter typed in putty takes 20 seconds.
Individually, they are fast. but both on the same network even with different IPs create a problem. Any suggestions to fix this.

Hi kartheek, this seams strange. Please send the "kern.log" files of the devices so that we can analyze the root cause. A Wireshark trace would also be welcome.

Just my guest but can you check if they MAC address is different? I once deploy a few pi based on the same backup image, forgot to run the factory-reset that cause multi device with the same MAC in the local network.

Dirk,
Can you please guide me how to get the logs.
Additional info:
I loaded the two pis with the same image.. When i am putting the two pis on the same network, i go to "/etc/dhcpcd.conf" file and change the static IP. Both have different IPs.
MAC addresses are different

Hello, please excuse the long delay. I have moved your topic to the Node-RED forum. I hope that the experts from erminas may support you.
