While upgrading Tomcat, Java and Lucee and also using ARR instead of BonCode, our Application runs as expected in terms of functionality. But we encounterd a performance degradation by 30%-100%. I did some testing using several Lucee Versions, different Tomcat Version and different Java JDK/JRE's:
Lucee 5.1.x to 184.108.40.206
Java JDK/JRE from 1.8 to 1.11 (zulu, adpot, oracle, openjdk, amazon)
No specific Lucee or Tomcat Version could be identified to be a reasonable factor for speed degradation. But as soon as Java > 1.8 (where applicable), the performance degradation is present.
I add some testscripts and images showing the results running them with Lucee 220.127.116.11. The only difference between them ist Java1.8 (~19ms) and Java1.9 (~25ms). This shows that Java 1.9 requires 130% of precessing time compared to Java 1.8 for the testscripts.
Running our Applications with Java 1.9 requires up to 200% of the processing time of running with Java 1.8. The timing/debugging data shows that almost everthing is slower, by which i mean i could not identify a single tag/function or feature/extension to use massively more time. Most of them run slower.
There is a thread regarding this in the forum:
Windows Server 2012 R2 Standard x64
Microsoft IIS 8.5
Microsoft ARR 3.0
Tomcat 9.0.17 x64
Oracle OpenJDK jdk-9.0.4 x64
Lucee 18.104.22.168 (lucee-22.214.171.124.jar)
No Installer used.
