Recently I've been having lag issues with Minecraft and it is concerning me because my computer can handle games that are far more demanding than vanilla Minecraft. I've tried to allocate more RAM because I noticed I only use 499MB out of 16GB. After trying to allocate 8GB with a 64-Bit java I get this error upon launch.

Open launcher->edit profile>JVM Arguments->make sure its check and says -Xmx3G -Xms3G
Yes, double.
Seeing you have 16GM of ram, I recommend using -Xmx3G -Xms3G, or -Xmx4G -Xms4G. Please don't insert higher numbers; it wont help, and whole PC may crash.
Also i see you are using Optifine, maybe something else too. Try launching minecraft with multiple GB disabling these files

Maj Zore // KATRERY
When doing this I get this crash error.
Error occurred during initialization of VM
Could not reserve enough space for 3145728KB object heap
I went to that file and I can't understand a thing that is in the notepad. You're no help.
Well if you don't understand it, might be a good idea to give us a look at it, don't you think?
