I personally like using patterns as functions in height_fields:
Note how fast this scene renders:


#include "colors.inc"


camera
{
 location <0, 2, 0>
 rotate 30*x
}


sky_sphere
{
 pigment
 {
  gradient y

  color_map
  {
   [0.5 rgb <1, 1, 1> ]
   [1 rgb <0, 0, 0> ]
  }
 }
}


light_source
{
 <-100, 100, -100>
 color White
}


#declare f_hills =
function
{
 pattern
 {
  bumps

  scale <0.1, 0.1, 0.1>
 }
}


height_field
{
 // Incease your resolution here if you need to.
 function 256, 256 { f_hills(x, y, z) }
 smooth

 pigment
 {
  color rgb <1, 1, 0.8>
 }

 translate <-0.5, 0, -0.5>
 scale <10, 0.5, 10>
}

#include "colors.inc"


camera
{
 location <0, 2, 0>
 rotate 30*x
}


sky_sphere
{
 pigment
 {
  gradient y

  color_map
  {
   [0.5 rgb <1, 1, 1> ]
   [1 rgb <0, 0, 0> ]
  }
 }
}


light_source
{
 <-100, 100, -100>
 color White
}


#declare f_hills =
function
{
 pattern
 {
  bumps

  scale <0.1, 0.1, 0.1>
 }
}


height_field
{
 // Incease your resolution here if you need to.
 function 256, 256 { f_hills(x, y, z) }
 smooth

 pigment
 {
  color rgb <1, 1, 0.8>
 }

 translate <-0.5, 0, -0.5>
 scale <10, 0.5, 10>
}
