Uniform

• Low page locality :
  PS < OS < PS-OO < PS-OA < PS-AA.
• High page locality :
  OS < PS-OO < PS-OA < PS < PS-AA.
• Contention grows as the square of transaction size.
• Here transaction size in pages decreases by 3 times, contention decreses by 9 times.
  
  

Tay's Result : Hence reducing transaction size by a factor of three for PS, reduces the contention by a factor of nine. Hence PS performs better.
