Description
Some days ago I found that code in twisted.protocols.basic.LineReceiver is not good optimized. You used string adding in dataReceived function. But string is immutable object, so in each addition you create new instance of String. When line too large and data chunks very small it consume too much recourses. I've create test example with array buffers, you can found it in attach.
