So I've recently gotten into tekkit classic and for the first few days we had no lag though a bunch of machines were running. However from the last 3 days I've had a lot of lag even when im playing alone. It takes me about 5-10 seconds to just open a chest. I've tried a lot of solutions such as turning down all of my settings, turning off my machines,etc. These are my specs
Dell Vostro 260s
4gb ram (32 bit)
i3 2120
java 7
My internet speed is 15 Mbps
Any help would be largely appreciated.
Ps: If you want to tell me to get a better computer then just dont
thanks for anyone helps me :D
