high CPU usage at startup

Post by mhanor »

Hi! With new RC build, the VirtualBox process seems to do some CPU intensive task (one core only), in the first few seconds from its creation. The COM process start and the Manager or VM window creation gets delayed by 5 seconds, on my PC (Intel i3 2120 @ 3.3GHz). Is it expected? Here's some monitoring, done with Process Monitor, from Microsoft Sysinternals. OS Windows 8.1 x64

Code: Select all

12:07:03,9673451	Explorer.EXE	3004	Process Create	C:\Program Files\Oracle\VirtualBox\VirtualBox.exe	SUCCESS	PID: 176, Command line: "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" 
12:07:08,8557728	svchost.exe	736	Process Create	C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe	SUCCESS	PID: 3024, Command line: "C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe" -Embedding
12:09:25,9948769	Explorer.EXE	3004	Process Create	C:\Program Files\Oracle\VirtualBox\VirtualBox.exe	SUCCESS	PID: 4136, Command line: "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" 
12:09:30,9308406	svchost.exe	736	Process Create	C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe	SUCCESS	PID: 4392, Command line: "C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe" -Embedding

Yes, that's expected. VBox on Windows is now doing a lot more checks at startup than older versions.

Then maybe it should give some kind of a feedback to the user. The new slow startup isn't comfortable, from my point of view. Or maybe there's room for improving the process startup.
