> StringBuffers are used through the code, but in a way that reduces their performance below, perhaps, what normal String concatenation would be.
> Doing
> StringBuffer s = new StringBuffer();
> s.append(a + b);
> is the same as
> StringBuffer s = new StringBuffer();
> s.append(new StringBuffer(a).append(b).toString());
> So, don't do normal concatentation in an append call, since one went to the trouble to use StringBuffer's in the first place.
