Project size and effect on editor start times

Hi
Just wondering why the larger your project the longer it takes to enter playtime. For instance if you have say 50 gigs in your project folder unity will take around 15 seconds from pressing the play button to actually starting (blank snene) whereas only having a couple gigs the editor will begin almost instant?. Does Unity have to search all the files each time you press play?
Is there any way, other than keeping the folder size as small as possible, to help the editor begin faster no matter the size of the project?
Thx

 

Profiling the editor is one way to shed some light. In doing so, a pretty decent chunk of the time to enter play mode is taken by by "ReloadAssembly", which I assume takes longer and longer the more code you have in your project. In my project, a bunch of time is also taken up by HDRP rendering cleaning things up, so perhaps the more materials in the project the more work it needs to do.

Anyway, you might take a look at the profiler results and make sure there isn't any 3rd party code doing anything time consuming. Otherwise, I don't know how to speed up the process overall.

 

Hey dg
So in your opinion then its not the mesh textures etc that cause the slow down but the code in the project even when that code is not been used in the scene been played?

 

Here are a few of my answers regarding EnterPlayMode issues. I would fire up the profiler and check what's slow. It's explained in the first link.

Cool thx for all those links I will get on them right away
