+🏗️ Work in progress 🚧
+
+
+This benchmark is designed for generic but comprehensive performance tests of the computing infrastructure at CMS Analysis Facilities. It currently includes the following functionality:
+
+- Multiple options for code execution:
+    - Sequential
+    - Parallelized via `concurrent.futures`
+    - Parallelized via `Dask` using local cluster
+    - Parallelized via `Dask` using Gateway cluster
+- Multiple methods of loading and reading columns from NanoAOD ROOT files:
+    - `uproot`
+    - `coffea.nanoevents`
+- Generic operations applied to data in columns:
+    - Nothing (just open the ROOT file with a given method)
+    - Load column data into memory
+    - Perform a simple operation on a column, e.g. `mean()`
+- Time profiling
+- Measuring size of columns in bytes
