 - I updated all the [DSpace helper Python scripts](https://github.com/ilri/DSpace/wiki/Scripts) to validate against PEP 8 using Flake8
+- While I was updating the [rest-find-collections.py](https://gist.github.com/alanorth/ddd7f555f0e487fe0e9d3eb4ff26ce50) script I noticed it was using `expand=all` to get the collection and community IDs
+- I realized I actually only need `expand=collections,subCommunities`, and I wanted to see how much overhead the extra expands created so I did three runs of each:
+
+```
+$ time ./rest-find-collections.py 10568/27629 --rest-url https://dspacetest.cgiar.org/rest
+```
+
+- Average time with all expands was 14.3 seconds, and 12.8 seconds with `collections,subCommunities`, so **1.5 seconds difference**!
