Hi Carter,
Are you running this on an AVX512 machine? Have you seen/tried to run
this on a machine that does not have AVX512, like AVX2 or even aarch64?
thanks

Hello,
TLS performance has appreciably regressed in JDK-18 and JDK-19 from
earlier releases using TLS_AES_128_GCM_SHA256 and
TLS_AES_256_GCM_SHA384 ciphers. I suspect the throughput reduction is
in part related to the substantial increase in allocation per
operation by roughly the size of the content transferred, even in
cases where the contents are provided using direct byte-buffers.
I've created a simple JMH benchmark using the socket API here:

JMH JSON results across JDK releases are located here:

I'm sorry if this has already been reported or is otherwise already
being tracked. Please let me know if additional information would be
helpful.
Best,
Carter Kozak
