Camera speed

here is the cs file. how to make it follow player faster? and can you convert it to java file?

using UnityEngine;

using System.Collections;

public class CameraFollow : MonoBehaviour

{ public float xMargin = 1f;
public float yMargin = 1f;
public float xSmooth = 1f;
public float ySmooth = 1f;
public Vector2 maxXAndY;
public Vector2 minXAndY;
private Transform player;
void Awake () { player = GameObject.FindGameObjectWithTag("Player").transform; }

 bool CheckXMargin()
 {
     return Mathf.Abs(transform.position.x - player.position.x) > xMargin;
 }
 bool CheckYMargin()
 {
     return Mathf.Abs(transform.position.y - player.position.y) > yMargin;
 }
 void FixedUpdate ()
 {
     TrackPlayer();
 }
 
 
 void TrackPlayer ()
 {
     float targetX = transform.position.x;
     float targetY = transform.position.y;
     if(CheckXMargin())
         targetX = Mathf.Lerp(transform.position.x, player.position.x, xSmooth * Time.deltaTime);
     if(CheckYMargin())
         targetY = Mathf.Lerp(transform.position.y, player.position.y, ySmooth * Time.deltaTime);
     targetX = Mathf.Clamp(targetX, minXAndY.x, maxXAndY.x);
     targetY = Mathf.Clamp(targetY, minXAndY.y, maxXAndY.y);
     transform.position = new Vector3(targetX, targetY, transform.position.z);
 }

}
