Two identical machines, 10 second boot time difference

In taskmanger startup if gives you the impact of everything at boot a good place to start

The "boot time" that windows references is simply the time it takes for the motherboard bios to hand things over to windows. As such they call it "last BIOS time".

What you could do is dig around in the bios and remove some Boot options within it, remove the ones that you would or could never use but if you plan to boot via usb for example at some time in the future, leave that one somewhere in the list. Example for MSI.

I did configure them a bit different from each other. Install this software package or that.

This could be your main problem/question. I do think your startup times are fine...

Hi dictum,

Both those start times are quite reasonable, however; I understand your interest in knowing exactly why they are different. This boils down to how much time are you willing to invest to potentially save 10-14 seconds.

Have you compared time to boot to Safe Mode on both PCs?



This link to a vbs script will provide a more exact boot time for comparison of regular boot times.

This post references the use of Microsoft AutoRuns and Windows Performance Analyzer to help understand startup delays.

How to optimize windows10 - XP still seems faster



I would suggest starting with AutoRuns first. If you watch the video, it will direct you where to look to identify startup delays. Also, you should be able to compare both PCs configurations a bit more precisely.

Then finally, Windows Performance Analyzer will show the entire details of the boot process in a graph format. This will clearly identify what portion of the boot process is different between the two PCs.

One caveat with WPA, the volume of data produced can be a bit overwhelming. Analyzing the results in order to effect positive results can prove challenging.

I have two identical MSI GT80 SLI machines, configured identically hardware wise and software wise also.
Well, there is one difference, one has lower bandwidth RAM than the other. 17000 vs 19200. Both have 32GB.

If the hardware could be identical, could you say the same about the software?

Are Windows 10 version the same?
Are all the Windows 10 updates installed the same?
Are the drivers version the same?
Are the services and startup programs the same?

It's not just a matter of hardware. the software also impact the boot time.

@dictum

Besides the obvious difference in the RAM speeds, does your BIOS have a setting similar to this?
And if so... are they set the same?
