Allocating more ram to application

[LWCARAB]

Hello,

I have a vb.net application that loads in a 155mb XML file, on my machine (Dual Core, 4gb ram) this process takes under a minute however the same process has is known to take up to 45 minutes on other machines, I have traced this down to the amount of ram available on the machine. I was wondering if there is a way to give memory priority to my application?

Thanks
