Advice Request Why is my M.2 SSD boot time is slow?

[sepik]

Hi,
I have Lenovo Desktop PC with M.2 256GB nvme. So it SHOULD boot faster that typical SATA SSD.
According to bootracer, my boot time is 25 seconds. Is it by desing of M.2 or wtf is going in there, because my friend oldie but goldie i3 notebook with 120gb sata ssd boots within 5-7 second to windows.
Finally found a solution. Managed to get 25 sec -> 15 second boot time reduction, because several folders in %windir% were "compressed" by the OS (system32 etc). So while booting, those folders and files within has to have uncompressed during bootup realtime.
So uncompressing those Folders saves 10 second of my boot time.
The Mystery is that why those folders was packed in a first place..
Oh well

Just a shot in the dark here, but check if "Compress this drive to save disk space" is checked under C:\ properties (normally it shouldn't):

NVMe boot speed is very slow because PCIe takes some time to initialise but that delay is somewhat reduced thanks to huge Read IO speed but eventually it results in slow boot on Linux,Windows and OS X. I have W10 on NVMe drive and it takes 15 secs-30 sec with only 4 apps at startup and have tried with 0 apps the same things happen.
I used SATA M.2 on Linux and it boots in 5 secs flat! And Windows should be similar too!

I have a Samsung M.2 with 91% free disk space, no compression, fast startup disabled, most services (like NVIDIA) except for MSI Afterburner and security programs disabled at startup. Here is my boot time--this also counts the amt of time Windows takes to get things together after the desktop loads.

Oh well, I'd rather have the fast disk rates than an extra 5 sec. shaved off startup, especially since one can't really improve unless you do fast startup. No way with that either.

My bootracer boot time is 16 sec, even with i have GData which causes some boot delays. Sure i have many programs that loads during boot up but i've used Avira SpeedUP Pro to make them "delayed start". This shaved off couple of seconds.

Doesn't really make a difference to NVMe it reads at a speed of 1GB/s or more so most apps are less than that!
