I am using net.Listen("tcp", addr) for a small server program which is to accept data and STORE it on the server. On the client side, I have a c++ program and I have simply written 4096000 BYTES to the socket (connected to my server program) The write on the client side finishes in less than a second. When using the Read() functions of the connection net.Conn, the read happens very slow.
Following is the Read() for loop :
// Handle the reads
var tbuf [81920]byte
for {
n, err := c.rwc.Read(tbuf[0:])
// Was there an error in reading ?
if err != nil {
log.Printf("Could not read packet : %s", err.Error())
break
}
log.Println(n)
}
return
c.rwc is of type net.Conn
The output of the above code is as follows :

As you can see the read operation is taking nearly 21-25 seconds to read 4096000 bytes, which is very slow as the server and the client are on the same computer. Is the read operation wrong ? I am unable to understand why is this so slow ?
