Windows 10: Anyone else losing overall speed from Bitlocker?

I have encrypted my drive 3 times, running a benchmark before and after encryption. I finally settled on 128 aes-xts default on Bitlocker. These tests were done with fresh installs of windows 10 home, and a windows 10 pro upgrade added right after with no other software installed on the computer.

The hard drive, Seagate Firecuda dropped from 117% to 86% overall performance.
CPU i3-7100 dropped from 71.5 to 69.2
The Nvidia 1050 Ti graphics card dropped from 39.4 to 34.1
Memory 8gb, no change.

The computer went from 88th performance percentile down to 56th. What a hit. With Veracrypt 256 aes encryption, the performance drop on my Dell and Gateway computers was only about 1-2%. I could not even notice it. Where as my brand new Acer with Bitlocker encryption was so noticeable, it prompted me to bench it. I thought I had a virus.
Bitlocker is a virus*Mad

Lost Windows 10 after restore. Now I am unable to get 10 again. What can I do?

Andre, thanks for you response and I'm sure that the solutions offered would have solved my problem but it came too late and I wound up taking the pc to the Geek Squad.

Thanks again,

Dennis

A couple months ago I purchased a Dell PC with 8.1. Downloaded the Windows 10 and operated for awhile. Had a problem (not with 10)and had to do restore and lost 10. Now I am unable to get 10 again. What can I do.

 

I find it hard to believe Bitlocker would affect your graphics and CPU benchmarks. Which benchmarks are you running? I have a spare Bitlocker system I can play around with.

 

I used these two:
Novabench - Free Computer Benchmark Software
Home - UserBenchmark

I'm wondering if the upgrade of 10 pro could possibly be the problem, as opposed to a standard installation of 10 pro.

 

No significant difference in my testing.

1. Reboot
2. Wait 5 minutes
3. Run Nova
4. Run UserBenchmark
5. Enable/disable BitLocker
6. Wait for encryption/decryption to complete
7. Go to 1

Thanks for your response.
It must be my upgrade, very few others have reported any slow downs either. I can't find anyone with a graphics card problem from Bitlocker encryption, lol. Maybe I'll just encrypt the OS with veracrypt and use encrypted volumes.
