FluentBit Performance

[brunooliveiramac]

Hi everyone :)
I'm receiving logs from 2 persistent TCP connections to fluentbit. This is my config.

apiVersion: v1
kind: ConfigMap
metadata:
  name: fluent-bit-config
data:
  fluent-bit.conf: |
    [INPUT]
        Name         tcp
        Listen       0.0.0.0
        Port         24224
        Format       none

    [SERVICE]
        Flush        1 
        Daemon       Off
        Log_Level    info
        HTTP_Server  On
        HTTP_Listen  0.0.0.0
        HTTP_Port    2020
        Health_Check On
        Mem_Buf_Limit 2GB 

    [INPUT]
        Name         tcp
        Listen       0.0.0.0
        Port         514
        Format       none
        Buffer_Size  1024KB   
        Chunk_Size   512KB
        Threaded      on
        Tag          syslogs 

    [INPUT]
        Name         udp
        Listen       0.0.0.0
        Port         514
        Format       none
        Buffer_Size  1024KB   
        Chunk_Size   512KB
        Threaded      on
        Tag          syslogs 
    
    [OUTPUT]
        Name         kafka
        Match        syslogs
        Brokers      kafka:9092
        Topics       syslogs
        Retry_Limit  False
        Format       json
        rdkafka.queue.buffering.max.ms 100  
        rdkafka.request.required.acks 1     
        rdkafka.message.send.max.retries 5  
        rdkafka.retry.backoff.ms 100
        Workers      10

I would need to handle:
~ 70MB per sec
~ 700 bytes per message
110.000 messages per sec

Not being able to reach full capacity

I don't have issues with forwarding, and my Kafka is working fine.

The point is, I still have CPU and memory available. I would expect Fluentbit to be able to handle more throughput.
If anyone know what can I do to improve its performance?
