Huge performance difference between Bootit BM and Bootit UEFI
Posted: Thu Sep 08, 2022 8:17 pm
I have a HP Deskpro 600 which supports both BIOS legacy and UEFI booting.
I prefer the BIOS legacy method and have installed Bootit BM. This works fine as I can create partions and install and boot operating systems.
However when I try to copy a partition or make an image with Bootit BM / Image for DOS the performance is very poor (more than 15 minutes for a 30 Gb partition).
The HP supports NVME SSD's and I have installed a M.2 NVME PCIe SSD. The SSD speed in Windows and Linux on this HP is great: read max. 3300 Mb/s and write speed 1800 Mb/s.
But I do not get this performance in Bootit BM. The device driver in Bootit BM seems not optimzed for my configuration. I have tried different settings like BIOS and BIOS direct, but the copy/image performance is poor.
I do not want to install Bootit UEFI but I have tested the performance using Bootit EUFI.
And to my suprise there are no issues here. Full use of the SSD speed.
I don't understand what is causing the difference in performance. I have tested with the latest versions of Booit BM and Bootit UEFI.
Did I miss an option in Bootit BM? I have kept everything default.
Why is Bootit BM so slow, whereas Bootit EUFI has no problems?
For now I keep Bootit BM installed and use an USB Stick with Bootit UEFI to do partition work when I need to.
Any help or advise is welcome.
