Could we replace apache mina with netty in openfire . If that is possible , how could we achieve this ?
Not easily, but why would you want to do this? Of course, with time and money, anything is possible!
Netty is more clean than apache mina and performance is better. Also mina is buggy as it disconnects clients suddenly without any reason.
That’s my impression too, but somebody would have to do the work / somebody would have to pay for the work to be done. Are you in the position to do either of those?
