Hello everyone,
After integrating SSL with Kafka, I noticed a significant decrease in producer
speed.
The speed of transmitting messages in plaintext is 101MB/s, which is exactly my
network's maximum bandwidth speed.
However, the speed of transmitting messages encrypted with SSL is only 19.17
Thank for your help,
It seems we have identified the issue.
Kafka SSL is based on the javax.net.ssl implementation, which only supports
single-threaded operations.
During encryption, only one logical thread is working on the CPU.
I am attempting to integrate other SSL implementations.
