Re : Cluster performance after enabling SSL
hi;
will enabling SSL (node-to-node) cause an overhead in the performance of
Cassandra? We have tried it out on a small test cluster while running
Cassandra-stress tool, and did not see much difference in terms of read and
write latencies.
Could somebody throw some light regarding any impact SSL will have on
large clusters in terms of performance. Thanks in advance.
Cassandra-version (2.1.15)
thanks
Sai

thanks Surabhi; we'll do further tests regarding this. The per node tps are
less, but for the overall cluster the tps are like 90k.

We have seen a little overhead in latencies while enabling the
client_encryption.
Our cluster gets around 40-50K reads and writes per second.

Read this:

It can cause bigger variances in latencies, but not much.
