Hello,
Is it faster to keep something as a variable for example:

private int walkSpeed = 5;
private int runSpeed = 10;

void Update()
{
    if(walk)
   {
        speed = walkSpeed;
   }
   else
   {
        speed = runSpeed;
   }

Or is it faster this way:

private int walkSpeed = 5;

void Update()
{
    if(walk)
   {
        speed = walkSpeed;
   }
   else
   {
        speed = walkSpeed * 2;
   }
}

the first one is faster the seocnd one will allocate less memory.
