Redisson vs Lettuce - Performance Comparison

I was just trying to do a simple performance test to compare Redisson and Lettuce. I really like Redisson. But Redisson seems to be consistently slower than Lettuce. Is this expected?

Redisson throughput = 58K requests / sec Lettuce throughput = 75K requests / sec

@RepeatedTest(10)
public void lettucePerformance() throws InterruptedException {
    RedisClient redisClient = RedisClient.create("redis://localhost:6379/0");
    StatefulRedisConnection<String, String> connection = redisClient.connect();
    RedisReactiveCommands<String, String> reactiveCommands = connection.reactive();

    long before = System.currentTimeMillis();
    Mono<Void> mono = Flux.range(1, 500_000)
            .flatMap(i -> reactiveCommands.incr("user:1"))
            .then();

    StepVerifier.create(mono).verifyComplete();
    System.out.println((System.currentTimeMillis() - before)  + " ms");

}

@RepeatedTest(10)
public void redissonPerformance() throws InterruptedException {
    RAtomicLongReactive longReactive = client.getAtomicLong("user:2");

    long before = System.currentTimeMillis();
    Mono<Void> mono = Flux.range(1, 500_000)
            .flatMap(i -> longReactive.incrementAndGet())
            .then();

    StepVerifier.create(mono).verifyComplete();
    System.out.println((System.currentTimeMillis() - before)  + " ms");

}

My Config:

I tried with this

            config
                    .setNettyThreads(0)
                    .useSingleServer()
                    .setAddress("redis://127.0.0.1:6379");

and this.

            config
                    .useSingleServer()
                    .setAddress("redis://127.0.0.1:6379");

@mrniko I could not get back to you. The performance looks good now.
