Thank you,
I should have mention hardware and software which I used in this experiment:
CPU: one Intel Xeon silver 4210 10 core 2.2G
Network: 1Gb
OS: Ubuntu 20.04.2 LTS
Java: 1.8.0_321 Oracle
Apache Cassandra 4.0.1
Data model is a single table:
text partitionKey, 15chars
int clust
the % numbers seen high for a clean network and a reasonable fast client.
The 5% really not reasonable. No jumbo frames? No network retries
(netstats)?

I wish there was an easy answer to this question. Like you pointed out it is
hardware dependent but software stack plays a big part. For instance, the JVM
you're running makes a difference too. Cassandra comes with netty and IIRC we
include tcnative which accelerates TLS. You could also slip Ama
The 3-5% penalty range is consistent with what other users have reported
over the years but I'm sorry that I can't seem to find the
threads/references so my response is unfortunately anecdotal.
More importantly, would you be interested in sharing your data? It would be
great to feature it as a blo
Hi,
Anyone measured impact of wire encryption using TLS
(client_encryption/server_encryption) on cluster latency/throughput?
It may be dependent on Hardware or even data model but I already did some sort
of measurements and got to 2% for client encryption and 3-5% for client +
server encry
