need help increasing walk speed

ve been using the locomotion script given by mixamo for my third person character and walking forward is really slow, but strafing and walking to the side is faster, im more confident in javascript and the code given is Csharp, this is the code:

 using UnityEngine;
 using System.Collections;
 
 public class LocomotionScript : MonoBehaviour {
     private Animator anim;
     
     // Use this for initialization
     void Start () {
         anim = this.transform.GetComponent<Animator>();
     }
     
     void OnGUI () {
         GUILayout.Label("CONTROLS");
         GUILayout.Label("Movement: W A S D");
         GUILayout.Label("Turn: Q E");
         GUILayout.Label("Jump: Spacebar");
     }
     
     // Update is called once per frame
     void Update () {
         float horizontal = Input.GetAxis ("Horizontal");
         float vertical = Input.GetAxis ("Vertical");
         //anim.SetFloat ("Speed", vertical);
         //anim.SetFloat ("Direction", horizontal);
 
         anim.SetFloat("Vertical", vertical, 0.15f, Time.deltaTime);
         anim.SetFloat("Horizontal", horizontal, 0.15f, Time.deltaTime);
 
         /*
         //Procedural rotation input, applied while moving. This allows turning without the need for turning animations.
         if (vertical > 0.05f){
             if(horizontal > 0.05f)
                 //this.transform.Rotate(Vector3.up * (Time.deltaTime + 2), Space.World);
             if(horizontal < -0.05f)
                 //this.transform.Rotate(Vector3.up * (Time.deltaTime + -2), Space.World);
         }
 
         else if (vertical < -0.05f){
             if(horizontal > 0.05f)
                 //this.transform.Rotate(Vector3.up * (Time.deltaTime + -2), Space.World);
             if(horizontal < -0.05f)
                 //this.transform.Rotate(Vector3.up * (Time.deltaTime + 2), Space.World);
         }
         */
 
         //Procedural rotation input for stationary turning
         if(Input.GetKey(KeyCode.Q)){
             anim.SetFloat("Turn", -1, 0.1f, Time.deltaTime);
             this.transform.Rotate(Vector3.up * (Time.deltaTime + -2), Space.World);
         }
 
         else if (Input.GetKey(KeyCode.E)){
             anim.SetFloat("Turn", 1, 0.1f, Time.deltaTime);
             this.transform.Rotate(Vector3.up * (Time.deltaTime + 2), Space.World);
         }
 
         else { anim.SetFloat("Turn", 0, 0.1f, Time.deltaTime); }
         
         //Pressing the space bar will cause the character to jump
         if (Input.GetButton("Jump")){
             StartCoroutine(TriggerAnimatorBool("Jump"));
         }
         
     }
     
     ///Triggers the bool of the provided name in the animator.
     ///The bool is only active for a single frame to prevent looping.
     private IEnumerator TriggerAnimatorBool (string name){
         anim.SetBool(name, true);
         yield return null;
         anim.SetBool(name, false);
     }
 }
