On further testing of this test case, weird results. Does this test work
for you? I get a mix of Actual counts. I ran this test on the full code and get
Actual 9996. I took out the limit, and got an actual of 9999. Not really sure
what's going on.
> GetFile becomes slow listing vast directories
> ---------------------------------------------

> Key: NIFI-5629

> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.6.0
> Reporter: Adam
> Priority: Minor
>
> GetFile repeatedly lists entire directories before applying batching, meaning
> for vast directories it spends a long time listing directories.
>
> Pull request to follow.
