hi
when i press f3 in the top left it says allocated memory 6% (443mb) and above it it says used memory 5% of 7282mb , how to increase them? i allocated more ram to minecraft to 8gb , so please how to increase it to 50% or more ?
Minecraft will not use more memory that it actually needs; it is actually wasteful to forcefully allocate gigabytes of memory because other programs can't use it; I only allocate 512 MB (half the default; -Xms512M -Xmx1024M, the latter is the maximum but I've never see it allocate more than the 512 MB to start with) and have never had out of memory; you only need more if you are running HD textures or lots of resource demanding mods (I use default except for a few customized textures and Forge with 10 mods and average around 300 MB; even on Amplified my settings work fine).
From what you have, it looks like you used only -Xmx to set an upper cap on memory usage and the game is allocating only what it needs (-Xms preallocates a set amount of memory, performance can be improved since it doesn't have to reallocate more/less as memory usage changes).
To sum up, more memory != better performance unless it is actually needed (the same is true for computers, I have 3 GB/32 bit, which some people would find low but I don't do memory-intensive work like video editing; note also that the Java process uses around 1 GB even though I allocate much less, since Java has a lot of overhead, not sure if it scales with higher amounts; e.g. 8 GB allocated = 16 GB used).

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
