Description

AutoSystemGC

This mod will automatically call System.gc() to free-up memory on your server and client!

Note:

System.gc() just tells the JVM to expend effort toward recycling unused objects. So sometimes System.gc() doesn't free memory.

Commands

/agc - the main command (alias)
/autosystemgc - the main command
/autosystemgc trigger - manually trigger memory cleanup
/autosystemgc reload - reloads the config as well as the mod

Config

Default config:

{ "cleanInterval": -1, "cleanThresholdPercent": 70.0, "memoryCheckInterval": 2, "logOnCleanTrigger": true, "broadcastOnCleanTrigger": false, "configVersion": 1 }

Details:

cleanInterval : scheduled memory cleanup (accepts numbers greater than 30, below that just disables the scheduled memory cleanup) (time unit is in seconds)
cleanThresholdPercent : the target memory threshold which then triggers a memory cleanup (accepts floats in a range of 0 to 100, value lower than 30 just disables this)
memoryCheckInterval : intervals for when to check memory usage percent (accepts numbers higher than 0) (time unit is in seconds)
logOnCleanTrigger : logs cleanup details when a memory cleanup is triggered
broadcastOnCleanTrigger : sends a server-wide message of the cleanup details when a memory cleanup is triggered
configVersion : this is an internal value. DO NOT CHANGE!
