With OpenSSL it is slightly faster than with JSSE, but again around 3 times slower than HTTP. Here are some details: Tomcat: 9.x nightly build tcnative: nightly build from master branch JDK: AdoptJDK 14 OpenSSL 1.1.1 11 Sep 2018 (this comes from Ubuntu 18.04 repos. I will try with a newer build) JMeter: 5.2.1 The application is Spring Boot 2.2.6 with REST GET/PUT/POST/DELETE endpoints that simply sets/gets data to/from Memcached. No usage of Spring Security! No redirects from HTTP to HTTPS! Let me know if you need more information!
