This indeed helped a lot! The average connect time dropped 10 times - now it is around 200ms! The median connect time is now similar to the HTTP times! Thanks a lot!

Re: Slow connect time with HTTPS
Hi, 1. Do You have Thread Group->same user… setting enabled or disabled when you see long connect time? 2. Do changing „same user…” setting make some difference?

Re: Slow connect time with HTTPS
Hello, Can you try setting this in user.properties: httpclient4.validate_after_inactivity=4900 httpclient4.time_to_live=12 And give us feedback Thanks On Thu, May 7, 2020 at 2:29 PM Martin Grigorov wrote: > On Thu, May 7, 2020 at 3:24 PM Martin Grigorov > wrote: > > > Hello, > > > > I face a strange behavior that I cannot explain to myself and I need your > > help. > > > > I use JMeter 5.2.1 to load test a Spring Boot 2.2.6 application with > > embedded Tomcat 9.latest. > > When using plain HTTP connector the connect time (& latency) are pretty > > low: > > - connect time: less than 1ms > > - latency: 2-3ms > > > > But when I use HTTPS (with Apr 1.7.x & OpenSSL 1.1.1f) the values are > > *much* bigger - around 3000ms. > > > > The application is running on host A and JMeter on host B, both in the > > same local network. > > The certificate is self-signed and registered in JDK's cacerts on both > > machines. > > The application exposes several REST endpoints without any > authentication. > > JMeter is configured to use Keep-Alive for the requests. > > I have the feeling it is related to the self-signed certificate but I am > > not sure. > > > > There is no such issue if I use 'ab' or 'wrk' - the connect is > > instantaneous for both http and https. > > > > Do you have any idea what could be wrong in my setup ? > > Thank you! > > > > To add: > - JDK 14 on both machines > - JMeter uses HttpClient4 > > Please let me know if you need more details! > > > > > > Regards, > > Martin > > > > > -- Cordialement.

Slow connect time with HTTPS
Hello, I face a strange behavior that I cannot explain to myself and I need your help. I use JMeter 5.2.1 to load test a Spring Boot 2.2.6 application with embedded Tomcat 9.latest. When using plain HTTP connector the connect time (& latency) are pretty low: - connect time: less than 1ms - latency: 2-3ms But when I use HTTPS (with Apr 1.7.x & OpenSSL 1.1.1f) the values are *much* bigger - around 3000ms. The application is running on host A and JMeter on host B, both in the same local network. The certificate is self-signed and registered in JDK's cacerts on both machines. The application exposes several REST endpoints without any authentication. JMeter is configured to use Keep-Alive for the requests. I have the feeling it is related to the self-signed certificate but I am not sure. There is no such issue if I use 'ab' or 'wrk' - the connect is instantaneous for both http and https. Do you have any idea what could be wrong in my setup ? Thank you! Regards, Martin
