How to speed up vkCreateInstance?

I am actually looking to a basic vulkan sample.
But I found that the apparition of the triangle pretty slow, so I took a profiler and it show me that the vkCreateInstance call take 596ms. For me this is surprising slow.
Is there a way to make it go much faster?
PS: The validation layer is disabled and the driver of my 980 GTX is update to date.

Download Vulkan Loader's source code and check what is going on in there.

Ok did a profile of the demo that comes with the LunarG SDK, and it takes only 60ms for the vkCreateInstance. I suspect that GLFW doing something wrong with required extensions.

vkCreateInstanceis not expected to be a hotspot, though 0.6 s is pushing it. Update to the latestest drivers from given GPU vendor website. If that does not help complain to the vendor.

I'm voting to close this question as off-topic becausevkCreateInstanceuse is quite straightforward. Either there is some user measuring error or misuse (that is not shared in the OP), or it simply takes that long and StackOverflow audience can do nothing about it, and it needs to be discussed with appropriate softwaredriver vendors instead.

I already wrote that I am using the latest driver version with an up to date LunarG SDK too,... Both sample compiled with same version of Visual Studio in release mode. Maybe I need to do investigations my self, but a more experienced user with VK should be able to point me how layers can impact performances due to the number of indirections,...
