How to make Minecraft lag less?

My computer really sucks and I really wanna play Minecraft with my friends. I've had this problem for a while now and this comp is Really old and outdated but I'm wondering if there's a way to boost it? I need a free solution so yeah. Please don't tell me to make the priority higher for Java.exe because it doesn't work. And I would use optifine but its not updated. Even when I have optifine I still lag so yeah. Here is the specs: RAM: 3GB Processor: Intel Core Duo CPU T2350 @1.86 GHz Graphics: Its like an Intel Chipset family?

Maybe its not lag. But if it is, make sure your Internet is good. But it could also be your frame rate. If you wanna make the frame rate faster and make the game run more smoothly, go to settings, make sure the render distance is low, the shading is low. If you want for info try to look up on google "how to make fps faster on minecraft" fps for frames per second.

Run it on compatibility mode, upgrrade drivers, get some more ram etc. Not much to do cause minecraft has poor optimization.
