You're best bet is to upgrade the storage from a spinning hard drive to a SSD. How much ram do you currently have?

If i upgrade the RAM

Given the age of the computer.

could i install the current IOS (high sierra)?

I don't recommend going to High Sierra, as it may be too damanding for the hardware. Just as an FYI, for Macs the operating system is called macOS. For iPhones and iPads, the OS is called iOS. Not a big deal, but just for your own education.

Edit: I fixed the title for you.
