My FTB Beyond server when I first started running it was using huge amounts of my CPU running up to all 4 cores however I have 6GB ram dedicated to it and after about 2 weeks of play with 2 people we cannot even open chests and get serious lag. PLEASE HELP
Other info:
set MIN_RAM=512M
set MAX_RAM=4096M
set PERMGEN_SIZE=256M
set JAVA_PARAMETERS=-XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+CMSClassUnloadingEnabled -XX:parallelGCThreads=2 -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10

Server Version: 1.10.2

try this instead

Code:
set MIN_RAM=5120M
set MAX_RAM=5120M
set JAVA_PARAMETERS=-XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -XX:+UseStringDeduplication

Thank you! That helped quite a bit, still the occasional lag but it works better now. The mobs still lag though. Any ideas?

nice, glad it helped! can't really give a general advice without more details, you can try a tool like warmroast or sampler to maybe track down the source
