Standard Assets no longer reducing compile time

In 5.4.f1 placing my scripts into Standard Assets, no longer reduces compile times like it did in 5.3.5.

It seems as though the Standard Assets DLL is generated each compile, even if the contents have not changed, which is incorrect behavior according to the docs.

I've created a reproduction project, that consists of 2000 C# classes.

TEST RESULTS

Unity 5.4.f1, using "Standard Assets": ~17 seconds compile time
Unity 5.4.f1, NOT using "Standard Assets": ~12 seconds compile time

Unity 5.3.5, using "Standard Assets": ~7 seconds compile time
Unity 5.3.5, NOT using "Standard Assets": ~12 seconds compile time

In 5.3.5, using SA reduced compile times by 40%. In 5.4.1 it actually increases them by 40%.

HOW TO REPRODUCE:

1. Open project, modify any line of code in SceneManager.cs
2. Observe compile times.
3. Rename "Standard Assets" to "_Standard Assets", wait for scripts to re-import.
4. Modify SceneManager.cs again
5. Observe compile times

ISSUES

• Using "Standard Assets" to store static scripts should reduce compile times, not increase them.
• Why is the compile time is as high as 7 seconds in 5.3.5? Although this is much better than the 12s without StandardAssets, it still seems much longer than it should be. Technically only 1 cs file needs to be recompiled here, so what is taking 7 seconds? If I delete the contents from Standard Assets, compile times drop to ~2 seconds.

Should be fixed in rc2 (5.4.0f2)

 

Excellent

 

This was a bug since 5.3 as well; I can verify it was just fixed in 5.3.5 patch 7 a few days ago; glad that fix is getting ported to RC2. Compile times are killing me... any time the compile is long enough to cause me to check Facebook my productivity becomes about zero.

 

Praise the lord it's been fixed! In 5.4.0f2 the 7 second compile times are back
