+## zome_call_single_value
+
+### Description
+
+Calls a zome function that returns a fixed value. This tests the maximum performance of zome calls when the zome
+function is not calling into Holochain other otherwise doing any work.
+
+### Suggested run
+
+```bash
+RUST_LOG=info cargo run --package zome_call_single_value -- --connection-string ws://localhost:8888 --duration 900
+```
