Really slow usb mount and file operations on usb

Hello fellow archlabs users!
I have a problem. Everytime I insert any usb device, I have to wait some minutes to mount. AFter mounting, copy is really slow. But the most important issue I have is the fact that when I try to eject it, There are processes that take aat least 2 cpu cores and never end.
Is there anything I could do to fix this frustrating issue?
Thanks in advance!

Have you checked the Arch Wiki? I think there is an entry in there for this issue. It’s a subsection of a more general topic - like troubleshooting automounting.
