AFAIK it's not the actual *call* of the method that is slow, but rather
attribute lookup and creation of bound method objects. If speed is of
the essence, code can cache the method object locally:

strio = io.StringIO()
write = strio.write
for element in elements:
    write(element)
result = strio.getvalue()
