> -------------------------------------------------
>
> Key: THRIFT-4102
> URL: https://issues.apache.org/jira/browse/THRIFT-4102
> Project: Thrift
> Issue Type: Bug
> Components: Python - Library
> Affects Versions: 0.10.0
> Reporter: Jin Yao
>
> I upgrade thrift from 0.9.3 to 0.10.0, and our rpc calls slow down.
> I digged around the code, and find maybe it caused by the write function in
> TBufferedTransport.
> The last line seems useless, but cost time.
> {code:title=TTransport.py|borderStyle=solid}
> def write(self, buf):
> try:
> self.__wbuf.write(buf)
> except Exception as e:
> # on exception reset wbuf so it doesn't contain a partial
> function call
> self.__wbuf = BufferIO()
> raise e
> self.__wbuf.getvalue() # it seems useless, but cost time
> {code}
