I have some more info that may help to explain why I am seeing a difference between the backup times using V5.4.2.5 and V5.5.2.1
The 2 PCs I have run the tests on previously are a 12thGen Intel i5 desktop and a 13thGen Intel i7 laptop.
Both of these CPUs have a mix of Performance and Efficiency cores. Its up to the thread director to allocate which cores perform which tasks.
I thought I would try the same tests on an older laptop with a 8thGen i7. This just has 4 regular cores with hyperthreading.
V5425:
Backing up to an internal SSD took 2m40s
Backing up an ext USB HDD took 6m14s
V5521:
Backing up to an internal SSD took 2m43s
Backing up an ext USB HDD took 6m14s
The external USB HDD was the same 2TB Toshiba device i have used in all my previous tests.
As you can see above, the backup times are now virtually identical between the 2 versions of Hasleo.
So, could my previous results be down to the way the cores are being allocated on 12th and 13th gen Intel CPUs?
I vaguely recall that you mentioned in another forum thread that you were developing using AMD based PCs which don't currently feature the mix of Performance and Efficiency cores like recent Intel devices do.
Anyway, food for thought.
