I trust you will preserve the functionality though?
I have used the buffer() function to achieve great leaps in performance
in applications which send data from a string buffer to a socket.
Slicing kills performance in this scenario once buffer sizes get beyond
a few 100 kB.
Below is example from an asyncore.dispatcher subclass. This code sends
chunks with maximum size, without ever slicing the buffer.
def handle_write(self):
if self.buffer_offset:
sent = self.send(buffer(self.buffer, self.buffer_offset))
else:
sent = self.send(self.buffer)
self.buffer_offset += sent
if self.buffer_offset == len(self.buffer):
del self.buffer
