This mod can call System.gc() periodically to clean up your memory.
It also adds the /memorysweep_c and /memorysweep_s commands to manually clean memory.
The default time interval of cleaning memory is 15 minutes, and you can modify it in the configuration file.
Memory can also be cleaned up by memory usage.(Default 75%)
If there is lag during garbage collection, please add the JVM parameter -XX:+ExplicitGCInvokesConcurrent
Of course, I also recommend trying out ZGC, which is newly added in Java 11 and does not require the parameters mentioned above:
-XX:+UnlockExperimentalVMOptions -XX:+UseZGC
Please do not use any other GC concurrently with ZGC and do not add -UseAdaptiveSizePolicy
