+# benchito
+
+Like [pgbench](https://www.postgresql.org/docs/current/pgbench.html) or [sysbench](https://github.com/akopytov/sysbench) but only for testing maximum number of connections. `benchito` will start multiple threads to issue very simple queries in order to avoid CPU or memory starvation.
+
+## Requirements
+
+* `make`
+* go 1.18
+
+
+## Setup
+
+Compile the `benchito` binary:
+
+```
+make
+```
+
+Start a PostgreSQL instance:
+
+```
+docker-compose pull
+docker-compose up -d
+```
+
+## Usage
+
+```
+./bin/benchito -help
+```
+
+## Cleanup
+
+```
+docker-compose down -v
+```
