             Summary: Add bufferSize processor configuration to PutFTP
                 Key: NIFI-4375
                 URL: https://issues.apache.org/jira/browse/NIFI-4375
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Koji Kawamura
            Assignee: Koji Kawamura


PufFTP is reported that it is significantly slower to transfer the same file compared with mput command.

It is less performant because it does not set buffer size of underlying org.apache.commons.net.ftp.FTPClient. The default buffer size is only 1KB.
Setting larger buffer size improves transfer rate.

{code}
To send 10MB file

# BufferSize = 1KB (default)
about 8 sec

# BufferSize = 16KB
about 300 ms
{code}

PutFTP should provide a property to specify a buffer size, and default value should be bigger.
