Hi,
This blog post talks about the reasons why Chromium/Chrome uses multiple processes :

CEF creates many threads and a few subprocesses when you visit a website to carry out several tasks (rendering, GPU, etc.) in a safer way but using more memory.
In order to create another process CEF can do 2 things :
- Run your application's EXE again.
- Run a different EXE.
The default behavior is running you application's EXE again and that's why you see your app several times in the task manager when you open a website. Something like this :
Code: Select all
MyApp.exe
MyApp.exe
MyApp.exe
MyApp.exe
If your app has a complex initialization or uses the DPR intensively, adding the GlobalCEFApp initialization can be complicated. In those cases it's recommended to use a different EXE for the CEF subprocesses. The task manager would look like this :
Code: Select all
MyApp.exe
SubProcess.exe
SubProcess.exe
SubProcess.exe
In theory, CEF can be used in a DLL too and for those projects you would need to use a different EXE for the subprocesses.
