You have lots of other options. One is to allocate a buffer outside the
loop for use in small messages, and allocate per-message for big messages.

msgbuf := make([]byte, 1024)

for ;; {
     msgsize = ....
     var buf []byte
     if msgsize > 1024 {
         buf = make([]byte, msgsize)
     } else {
         buf = msgbuf[:msgsize]

You could get arbitrarily more complicated if you care. You probably

Why can't you allocate buffer1 outside the outer for loop?
the buffer should be allocated and empty every time the server
receives a message because the buffer will recover the message received.
and i can't allocate a buffer with a huge capacity , it's a loss of
memory and also i can't predict the size of the buffer.
