Subject [jira] [Created] (NIFI-4375) Add bufferSize processor configuration to PutFTP
Date Mon, 11 Sep 2017 05:47:00 GMT
Koji Kawamura created NIFI-4375:

             Summary: Add bufferSize processor configuration to PutFTP
                 Key: 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
The default buffer size is only 1KB.
Setting larger buffer size improves transfer rate.

To send 10MB file

# BufferSize = 1KB (default)
about 8 sec

# BufferSize = 16KB
about 300 ms

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