Daniel Kulp commented on CAMEL-17019:
-------------------------------------
I did some more testing and it looks like it's just the JDK/JIT ramp up time.
If I increase the count in the test to 2000 (to make sure the JIT triggers) and
copy the enter testMock() method to a second testMock2() method (so the entire
test runs twice), you can see that the first run is definitely longer on Java11
than Java8 with both Camel 3.11.1 and 2.24.2. However, the second run is very
close between Java11 and Java8.

> - using JDK11: {{mvn clean test -Dcamel.test=3.11.1}}
> We have these results:
