Review Comment:
   I've upped the buffer size from 16 to 64KiB; this is solely based on manual 
performance testing. A typical TLS plaintext payload is 16KiB, so the buffer 
needs to be at least 16384.
   
   This does not mean websocket packets will be all 64KiB, but upto/max 64KiB. 
Before the fix, they were max. 200 bytes which cause slowness in desktop based 
consoles. Now, this is increased to up to 64KiB.
