 Some simple benchmark scripts for the package. Use them as they are or modify them to test specific scenarios.
 
-Example:
+Example with Redis:
 
 ```
-mix run benchmarks/flag.exs
+rm -r _build/dev/lib/fun_with_flags/ &&
+PERSISTENCE=redis CACHE_ENABLED=true mix run benchmarks/flag.exs
+```
+
+Running the benchmarks with Ecto:
+
+```
+rm -r _build/dev/lib/fun_with_flags/ &&
+PERSISTENCE=ecto RDBMS=postgres CACHE_ENABLED=false mix run benchmarks/persistence.exs
