Very Low FPS

Hi!

I have very very low fps in my game. My creatures have behaviour script attached and if i remove this script or at least Update() functions fps will become normal.

So suggest me please something to fix in my code to make fps higher!

   // Update is called once per frame
     void Update()
     {
         if (gameObject.transform.rotation != spawnRotation)
         {
             //this.gameObject.transform.rotation = Quaternion.AngleAxis(rotOffset, Vector3.up);
         }
 
         if (networkView.isMine)
         {
             if (target != null && isAlive && startAggro && target.GetComponent<Player>().isAlive)
             {
                 Attack(target);
             }
         }
 
         Die();
 
         curHP = Mathf.Clamp(curHP, 0, maxHP);
 
         if (isAlive)
         {
             if (checkForReAggro && attackersList.Count > 1)
             {
                 StartCoroutine(AggroDontHitRecovery(attackersList.Last()));
 
                 if (toggleToOtherTarget)
                 {
                     AdjustTarget(attackersList.Last());
                     toggleToOtherTarget = false;
                 }
             }
 
             if (_bUpdateRestoreHpAfterRunaway)
             {
                 StartCoroutine(WaitAfterRunAwayForRestore());
                 _bUpdateRestoreHpAfterRunaway = false;
             }
 
             else
             {
                 _bUpdateRestoreHpAfterRunaway = false;
             }
         }
     }
 
     void LateUpdate()
     {
         if (_allowWaypointMove && isAlive && GameObject.Find("MainCamera").GetComponent<Server>().connected) //!It used to be in FixedUpdate 11.01.15 / 0:12:00
         {
             WaypointMovement();
         }
     }
 
     void FixedUpdate()
     {
 
         if (isAlive)
         {
             Aggro();
         }
 
         if (networkView.isMine)
         {
             networkView.RPC("AdjustThePos", RPCMode.AllBuffered, this.transform.position);
             networkView.RPC("AdjustTheRot", RPCMode.AllBuffered, this.transform.rotation);
         }
 
         if (GameObject.Find("MainCamera").GetComponent<Server>().connected && this.gameObject != null)
         {
             if (isAlive)
             {
                 networkView.RPC("AdjustSpeed", RPCMode.All, (transform.position - lastPos).magnitude);
                 networkView.RPC("SendFloat", RPCMode.All, "Speed", speed);
             }
         }
 
         if (target != null)
         {
             if (!(target.GetComponent<Player>().isAlive))
             {
                 networkView.RPC("KilledTarget", RPCMode.All);
             }
         }
     }

And WayPoint movement:

   public void WaypointMovement()
     {
         if (networkView.isMine)
         {
             wayPointMovementTime += Time.deltaTime; //current?
 
             if (_flagWayPoint1)
             {
                 wayPointRot = Random.Range(0, 360);
 
                 transform.eulerAngles = new Vector3(0, wayPointRot, 0);
                 _wayPointDir = transform.TransformDirection(Vector3.forward); //Skipped
                 _timeRadius = Random.Range(0.1f * wayPointMaxRadius, wayPointMaxRadius);
 
                 /*if (networkView.isMine)
                 {
                     networkView.RPC("AdjustTheTimeRadius", RPCMode.AllBuffered, (float)Random.Range(0.1f * wayPointMaxRadius, wayPointMaxRadius));
                 }*/
 
                 _flagWayPoint1 = false;
             }
 
             if (!_flagWayPoint1 && wayPointMovementTime < _timeRadius)
             {
                 _flagWayPoint2 = true; 
                 _wayPointDir.y -= 20.0f * Time.deltaTime; //gravity
                 _controller.Move(_wayPointDir * Time.deltaTime * wanderingSpeed);
             }
 
             else
             {
                 if (_flagWayPoint2)
                 {
                     StartCoroutine(DoTheWay());
                     _flagWayPoint2 = false;
                 }
                 //wayPointMovementTime = 0;
             }
         }
 
         else
         {
             this.gameObject.transform.position = wayPointClientPos;
             this.gameObject.transform.rotation = wayPointClientRot;
         }
     }
 
     IEnumerator DoTheWay()
     {
         _nextGoTime = Random.Range(2f, 9f);
         /*if (networkView.isMine)
         {
             networkView.RPC("AdjustTheTimeStand", RPCMode.AllBuffered, (float)Random.Range(2f, 9f));
         }*/
         yield return new WaitForSeconds(_nextGoTime);
         _flagWayPoint1 = true;
         wayPointMovementTime = 0;
     }
