Description Dongha Paek 2024-04-29 23:35:12 UTC 
We need bigger buffer for UDP, as Azure customers are reporting network performance issue due to buffer being overflown.

 
Solution: Update Sysctl.conf in distro images to reduce UDP loss.
 
root:~# vi /etc/sysctl.conf
//add these lines
net.core.rmem_max = 1048576
net.core.rmem_default = 1048576
