![]() But, there may be something I forgot to account for, and as such, I'd like to hear from you if I failed to state smth. It is additionally considered as an authority reference execution of a Java Standard Edition since rendition SE 7. Lower ram usage and everything else is decent. OpenJDK In actuality, OpenJDK is a free and open-source execution of the Java Development Services Edition. For a while, I saw that Vanilla's memory use went up SUPER FAST to 80% while Lunar went up slowly and when it reached about 35% and then the GC kicked in and brought that to 15%, restarting the cycle.įor Minecraft at least, Zulu seems to be the best option. ![]() ![]() The spikes are HUGE on Oracle, while there are more memory usage spikes on Zulu, they are 3-5x smaller than the peaks of Oracle. Oracle's propriety one has a different license, uses different libraries and has a few little tweaks so Oracle can. OpenJDK is open source and anyone can use it without express permission. Then in light blue we have Oracle and in blue we have Zulu. There are other propriety JDKs but they all adhere to the same standard and many of them are built on top of OpenJDK. Green is OpenJDK, absolutely maxing out everything. However, in terms of memory usage, I was shocked.According to what I read, GraalJDK, the worst performer, loads much more stuff than any of the other 3. Zulu won in terms of garbage collection.OpenJDK (Not relevant for this post) was the most responsive of all 4, with Oracle behind, and then Zulu.Oracle's CPU usage was the lowest of all 4 (That actually compares Oracle JDK, OpenJDK, Zulu and GraalJDK).But if you do, I think you'll like it, maybe?)Īlso keep in mind this wasn't testing MC, but it gives us a rough idea of WHAT to expect. I took data from this: (warning, there are some advanced things here you may not understand. Now, why Oracle JDK and Zulu? Well, simple! Minecraft Vanilla and Badlion use OracleJDK while Lunar uses Zulu. OpenJDK is released under license GPL v2 wherein Oracle JDK is licensed under Oracle Binary Code License Agreement. Note that, unlike the past, Oracle JDK is not 'better' than the OpenJDK build (as long as both are at the same level as the security patch). And when combined with enterprise support, OpenJDK performance is top-notch. OpenJDK is an open source implementation of the Java Standard Edition platform with contribution from Oracle and the open Java community. The OpenJDK builds are becoming more stable with the contributions of the OpenJDK community. OpenJDK's performance is continually improving. And in MC, where RAM usage is a problem, you can see why I'm talking about this. Oracle JDK performance used to be better than OpenJDK, but that is changing. However, JDK is what use used to power MC and you may not believe, but different JDKs from different companies can lead to better or worse performance. "But Nyxw, this is not a programming forum" blah blah blah, I know.
