[oXygen-user] huge memory usage

[Dan Caprioara]

Hello Lars,

You can try to lower the memory limit to 128MB or bellow, by using 
-Xmx128m. 
You can change this both in the oxygen.bat file and in the oxygen.ini 
file from C:\Program Files\Oxygen 5.0\ directory, the entry: "Virtual 
Machine Parameters".

Probably the JVM is preferring to allocate memory up to the specified 
limit of 256MB instead of invoking the garbage collector. Because of 
this some sections of the RAM can be swapped out on the disk, creating 
delays.

Let me know if this change has solved the problem.
Best regards,
Dan
