Hardware • Re: NVME SSD slower on Kernel 6.1.0.20 than 6.1.0.18

I have repeat tested and acknowledge that on my system also the numbers move around a bit, maybe 10% +/-

The buffered disk reads are consistently slower on newer kernels, though:

6.1.0.18 --- 2524 MB/sec
6.1.0.20 --- 1851 MB/sec
6.6.13 --- 1660 MB/sec

Now all of this would just academic by I see it in actual usage also. I can copy a large file from the internal NVME to the Sandisk Extreme Pro.

6.1.0.18 950+ MB/sec
6.1.0.20 550 MB/sec
6.6.13 690 MB/sec

Also deleting a Virtualbox snapshot which is very disk heavy takes "a long time" on the newer kernels.

There must be a difference.
