Hi Marcin- I don’t know of any recent (and reliable) benchmarks. In general, we expect 1-2% impact on CPU utilization and a minor lag in latency — if not completely negligible impact in practical real-world scenarios where consumer code is performing tasks.
SSL adds a bit of CPU overhead, but today’s processors are magnitudes faster than the disk I/O and network I/O which tend to be the performance factors for messaging and event-driven systems. Are there specific concerns or features of your use case where SSL performance is noticable? -Matt Pavlovich > On Aug 1, 2022, at 4:00 AM, Marcin Giedz <marcin.gi...@arise.pl> wrote: > > Hello, are there any metrics /stats to show potential performance downgrade > when SSL is enabled between broker and client versus non-SSL ? > > Thx > Marcin
