I also have such sloweness in my program when the size of it become big. I see such problem at program size biger than 10Mb. Yes, I have old PC.

As for me, I divide my program on the small parts that suits me.
You can use such O-codes: "o<myfile> call" in main program.

What program are you using for generating G-code? Some programs can divide G-code files automatical after making correspondent settings in post processor.

It was my solutins. But new update of linuxcnc - v.2.7.15 looks like loads faster. Have you tried it?

I'm on 2.8 now. However I just ordered the component of my new pc, so i'll test again with a pc with at least enough ram to fit the program and i'll decide what to do.
Dividing the program isn't that easy on a 3d printer, but I guess I could write a script myself if I need it.

I tryed.
It helps, but i still fill 1GB of RAM and my pc starts swapping.
I'll try again as soon as i receive my new motherboard with 8GB of ram
