Sebb updated NET-505:
---------------------
Priority: Major (was: Critical)
> User specified bufferSize reset to default when FTPClient is disconnected or
> reinitialized resulting in performance degradation
> -------------------------------------------------------------------------------------------------------------------------------
>
> Key: NET-505
> URL: https://issues.apache.org/jira/browse/NET-505
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 3.2
> Reporter: Sean Kelley
>
> The __bufferSize member variable is reset in the __initDefaults() method.
> This method is called from the FTPClient's constructor, _connectAction_,
> reinitialize, and disconnect. This can happen when the FTPClient is re-used
> after the remote server closes a session due to a timeout, for example.
> If the bufferSize is set by the user via the setBufferSize() method, the
> value is lost when the buffer size is reset. Since the default buffer size
> controls the amount read from the input stream and written to the output
> stream, and is so low by default (1024B as defined by
> Util.DEFAULT_BUFFER_SIZE) the performance of FTPClient drops dramatically.
> The recommendation would be to initialize __bufferSize to zero when it is
> declared and then remove the assignment in __initDefaults().
