+## Benchmark Comparison
+
+The results of the benchmark are good:
+they show that ksql is in practical terms,
+as fast as sqlx which was our goal from the start.
+
+To understand the benchmark below you must know
+that all tests are performed using Postgres 12.1 and
+that we are comparing the following tools:
+
+- ksql using the adapter that wraps database/sql
+- ksql using the adapter that wraps pgx
+- sql
+- sqlx
+- pgx (with pgxpool)
+- gorm
+
+For each of these tools we are running 3 different queries:
+
+The `insert-one` query looks like:
+
+`INSERT INTO users (name, age) VALUES ($1, $2) RETURNING id`
+
+The `single-row` query looks like:
+
+`SELECT id, name, age FROM users OFFSET $1 LIMIT 1`
+
+The `multiple-rows` query looks like:
+
+`SELECT id, name, age FROM users OFFSET $1 LIMIT 10`
+
+Keep in mind that some of the tools tested actually build
+the query internally so the actual query might differ a little
+bit from the example ones above.
+
+Without further ado, here are the results:
