Untiy 5.0 performance questions

So I tried to upgrade my project from Unity 4.5 to Unity 5.0.
After that happened, I noticed my character responce was very sluggish.

I am creating an authoritarian server and having the players RPC their commands to their hero.
Now I am not so vain to think my code is perfect but my question here is why did it work great in Unity 4.5 (in fact I had to skip 4/5 update cycles) and it perform so horribly with Unity 5.0?

The only suspicion I had was regarding the module access. I could be wrong but this is what I thought was going on in C#:
<Old method>
this.rigidbody - a pointer to a module that Unity assumed would be there.
<New Method>
this.gameobject.getComponent<Rigidbody>() - a template function that would search for that type of variable inside the game object.

Now I understand the dilemma for not allowing the old method, but won't it take far more CPU cycles to invoke the template function rather than look for the pointer. I could be wrong, but I can't think of any other reason I would get such horrible performance.

I am currently working on a game that I want to release for an Indie startup. Before I make the choice to commit to 5.0 I need to understand whats going on here.

Thank in advance,

if you're using the component often, you should cache it and only call the .GetComponent<Rigidbody>() from Awake or Start,

 

Code (CSharp):

1. Rigidbody m_rigidbody;
2. void Awake() {
3. m_rigidbody = GetComponent<Rigidbody>();
4. }
5. void Update() {
6.  // use m_rigidbody instead of this.rigidbody
7. }

 

Considering Unity 4 looked the component up internally, I doubt this is the reason you're experiencing slowdown. Use the profiler freely available to you instead of guessing.

 

Thanks, Shkarface I will give that a try. I am still curious why it worked so well in 4.5 though.
Mr. Hippocoder, noob question where would I find this profiler?

Thanks,

Never mind found it. I will look at it.

 

Thanks to both. Thins are running much smoother now. I had no idea about the profiler!

 

Sort the profiler columns by Time MS - then when you play, you get to see which scripts take up the most time at the top. There's also deep profiling etc - just check the docs.

 

I didn't remember that the Profiler is now free
