Two processes sharing the same UDP port for sending

My application consists of a UDP server receiving high traffic.

I am thinking to increase the capacity throughput of the application and threading is not an option. So multiple instances of the same process is considered.

I was thinking whether it is possible to reuse the exact same UDP socket for sending out traffic between two different processes. I am interested only for sending since receiving is handled in another way.

Will setting option on socket to SO_REUSEADDR help here?

You can not create two servers in two different process because second request for binding on same port will be failed so you have to use SO_REUSEPORT option which allows socket to bind follow Let two UDP-servers listen on the same port? for your reference.
