I'm using RedisRateLimiter, but TPS drops a lot

[Sunywdev]

I used RedisRateLimiter, but the TPS dropped very sharply, from 1400TPS to 700TPS, my version is 3.0.3, the response time of the interface has been improved from 29ms to 79ms, the back is just an empty interface without any processing logic, what should I do? What can be done to optimize him? Thanks

Probably because RedisRateLimiter needs to communicate with redis for per request, which increases the time
