Summary0017002: CentOS 8 USB drive access extremely slow (40KB/s)
DescriptionI've installed CentOS 8 onto a Wyse 5060 thin client to a USB flash drive (again, thin client, no hard drive) to test running CentOS 8 on it. Everything about the USB is almost impossibly slow; so I tested flash drive access with dd. I used a variety of block size and flag settings and consistently got a write transfer rate of about 40KB/s. Tests were performed using /dev/random as the "if" and a second flash drive as the "of".

I looked in dmesg and messages and found no errors: the system identifies the drive and loads the xhci_hcd driver.
Steps To Reproduce1. Install CentOS 8 onto a Wyse thin client using a flash drive as the "hard drive".
2. Observe length of time any operation (especially writes) take. Simple OS updates take hours.
3. Use dd as performance test to duplicate my results.
