tekkit not using the memory it should be

[nefotcir]

i have it set so tekkit can use up to 2Gb of data, but when ever i go into a pack its only using 500 or so. i know that it needs more then this because the percentage always starts at 76 percent builds up to 89 percent and then lags. so is this a java error or tekkit. i would love to know how to fix this.

What you are seeing is the different between internal and external references to RAM/Heap allocation for the JVM (Java Virtual Machine). Externally you have a single process that is managed by the operating system and the memory usage shown is the total space used for both the programs/threads running inside the JVM and the overhead required to manage them. Internally you get different numbers depending on how the thread are allocated inside the JVM and those will fluctuate depending on Garbage Collection (GC), how many users are currently on, how many chunks are loaded, how busy certain mods are, etc.

 

There are about as many ways for lag to creep in as there are stars in the sky. You will need to do more work to isolate the source before blaming your memory allocations.
