Is there any Redis Library for Netty?

I am writing a Rest Service on Netty Framework which uses Redis to get some data.
I am looking for a Redis library that can be used with Netty.
I tried Jedis& Lettuce and both are impacting the performance(QPS) very badly almost it makes it half. I am executing only 2-3 hget commands per Http Call.

Lettuce:

I tried getting the StatefulRedisConnection and tried with both async and sync. Both there was no luck in performance improvements.

There is very little documentation online regarding Redis with Netty.Need some help in tuning or using Lettuce with Netty or some Netty specific RedisClient/Library.
Any help or useful links are really appreciated?
