Hi Manuel The results were stripped from the email. Can you send me a high level summary in text? We're currently running into this issue on my project.
Thanks Dominique Bessette -----Original Message----- From: timita <tim...@gmail.com> Sent: Thursday, October 17, 2019 3:54 PM To: geoserver-users@lists.sourceforge.net Subject: [Geoserver-users] Which Java 8? A quick benchmark Since Oracle's long-term support JRE 8 is not available for free anymore, we needed to find an alternative that is just as performant. The advice on this page <https://docs.geoserver.org/latest/en/user/production/java.html> might seem outdated, but there is still truth in it: in our experience OpenJDK 8 has always been outperformed by Oracle JRE 8. So we ran a quick and dirty benchmark using jMeter and the multiscale approach described here <https://geoserver.geo-solutions.it/edu/en/enterprise/jmeter.html> , for Oracle JRE 8, OpenJDK 8 (as available here <https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa> ), AdoptOpenJDK (Hotspot), and Amazon Corretto. *Environment:* Ubuntu 16.04 LTS GeoServer 2.15.0 Marlin 0.9.4.2 Native JAI and ImageIO *JVM options: * I cannot give details about the dataset used, as it's confidential - initially, we did not plan to publish these results. But the numbers should be telling. And here are the results. See this page <https://jmeter.apache.org/usermanual/component_reference.html#Aggregate_Report> for an explanation of the header, although not all of those columns are present in my reports. There's always room for debate, but /Average/ and /Throughput/ should give you a rough idea. So it turns out, at least in the realm of Java 8, AdoptOpenJDK and Amazon Corretto are viable alternatives to Oracle JRE. We are not rushing to upgrade to Java 11 yet, but it will be interesting to see if the difference between Oracle JRE and the "stock" OpenJDK still stands. I hope this is helpful to those who still need to run on Java 8.
