This tweak allows you to specify the quantity of new memory that Java can consume before garbage collection is initiated. Garbage collection (GC) consumes a lot of system resources and can severely affect performance.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'Generation0Size' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.

Note: Only functions with Microsoft VM build 3229 or greater.


(Default)	REG_SZ	(value not set)

Settings:

System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM]
Name: Generation0Size
Type: REG_DWORD (DWORD Value)
Value: Size in bytes (max = 4194304)
