Internet / SSD speed is slow

[Bartfalvy Gabor]

I have been using a hackintosh system built and installed by myself for 5 years.
I always update to the new operating system and always with a clean install.
I'm now using the Sonoma system and so far I haven't had any problems with the current or older systems.

Recently, my SSD and internet usage have been very slow. Interestingly, using Desktop is fast, but when I have to move data (copy/compress/download...), the speed drops drastically and I mostly get beach ball.
I've already tried reinstalling the system, several opencore versions and even returned to an older system (BigSur) once.
To my surprise, nothing improved the situation.

Once again, my hackintosh machine/operating system worked almost perfectly for years.
Information about my machine:
OC 0.98 / latest KEXTs / Sonoma 14.2 / i3-8100 / Crucial Ballistix Sport 32 GB / Crucial BX500 240GB SSD

Thanks in advance for ideas and help

Thanks. I don't even understand then, I haven't had such a problem for years?
So far, the Crucial SSD has been lightning fast. In several places, Samsung SSDs are not recommended.
SanDisk, Kingston, Gigabyte, would that be good?

Samsung SSD AHCI is recommended, just avoid Samsung NVME.
