Faster Debug.Log
An article by 
Debug.Log() slows down your editor or even hangs if it happens to run inside some long loop,
but you can make it faster by disabling stacktrace from Debug.Log()! (see image above)
Tested for-loop with 100000 iterations in editor (Unity 2018.1.6f1)
– 25000ms with stacktrace enabled
– 2200ms with stacktrace disabled
code used for measuring:
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

| // measure debug.log with large loop | |
| using UnityEngine; | |
| public class LogSpamTest : MonoBehaviour | |
| { | |
| void Start() | |
| { | |
| var stopwatch = new System.Diagnostics.Stopwatch(); | |
| stopwatch.Start(); | |
| for (int i = 0; i < 100000; i++) | |
| { | |
| Debug.Log(i); | |
| } | |
| stopwatch.Stop(); | |
| Debug.Log("Timer: " + stopwatch.ElapsedMilliseconds); | |
| stopwatch.Reset(); | |
| // with stacktrace = 25000 ms | |
| // without stacktrace = 2200 ms | |
| } | |
| } |
