LENOVO IdeaPad Slim 5 memory performance issue?

[erfan]

In some previous post I mentioned, that my plasma6 system on LENOVO IdeaPad Slim 5 15ARP10, AMD Ryzen 7 7735HS hangs for 15-20 seconds when copying a single image form gwenview. This hanging is only 5 seconds on an Intel based DELL Vostro 15 3530.

I would add here too, that to load a movie into avidemux on Lenovo take 15 sec, and on Dell 4 sec, the same movie in same conditions.

These differences made me wonder. I never done tests regarding the hardware, so I am little bit in the dark, but at one single simple sysbench test the Lenovo performed very-very bad. On the others performed better than the DELL. Running

sysbench memory run

I thought that I am not seeing well. It was even 15x-20x worst than my 14 years old Toshiba laptop.

On Lenovo the result shows a transfer speed between 170 MiB/sec and 240 MiB/sec. It is correctly written: one hundred seventy to two hundred fourty.

On Dell Vostro can be even 11159.89 MiB/sec, or on a 14 years old Toshiba it was around 3400 MiB/sec.

Do I interpret correctly, that the Lenovo's results are bad? Are these results, numbers relevant? If yes, how can I have on the bright new Lenovo these small results? Is this related to those long hanging times on generating thumbnails in klipper or video loading time in avidemux?
