unbearably slow modpacks

[RussianRoyal]

All modpacks including modpacks built into the technic launcher run at pretty much 0 fps. When loading up modpack the loading screen starts out black, and always never responds. One the modpack in loaded the whole modpack is super slow to a point of about a 5 second delay of the mouse on the screen. I have tried many things that I could think of that might fix this problem. Such as uninstalling technic, I have even reset my computer to try and fix the problem but the slow modpacks still continue. I dont see ram as a problem as I have allocated 5gb of memory to the launcher. I would like any help I can get to fix this problem. I would be much appreciated. Thanks

that's part of the problem. Java can't handle more than 3GB

Issues with the launcher belongs in Bug Reports. Post there if after lowering that RAM doesn't work

I've lowered launcher to 4GB,but the problem still is persisting.
