Simon Suo commented on KAFKA-2431:
----------------------------------
Hi all. This is Simon, a data infra intern working on LinkedIn's Kafka team. I
am currently evaluating solutions to reduce performance overhead of Kafka
security features.
The summary report here discusses the possibility of a optional OpenSSL
implementation that may achieve 4 to 5 times speed up. Is this being developed
right now? Do you have any additional benchmark data to show the potential
performance gain?
Let me know if you have any relevant information and time for a small
discussion. I can be reached at s...@linkedin.com
Best regards,
Simon Suo

> Test new Producer and new Consumer performance with and without SSL/TLS once
> the SSL/TLS branch is integrated.
> The ideal scenario is that SSL/TLS would not have an impact if disabled. When
> enabled, there will be some overhead (encryption and the inability to use
> `SendFile`) and it will be good to quantify it. The encryption overhead is
> reduced if recent JDKs are used with CPUs that support AES-specific
> instructions (https://en.wikipedia.org/wiki/AES_instruction_set).
