Awful Linux Guest Performance

Description
I just tested 64bit VBox 6.0.20 and 6.1.6 with a 64bit Linux guest on a 64bit Linux host (updating Guest Additions each time). Started at 6.0.20, performance was fine. Upgraded to 6.1.6, performance was so bad that the VM is unusable. Downgraded back to 6.0.20, performance is normal. So, VBox 6.1 is broken for Linux guests because of the awful performance.
Host: Intel Core i7 (1st gen) 28G RAM Guest: 2 cores, 4G RAM
Logs for both the broken 6.1.6 guest and the working 6.0.20 guest are attached.
I ran this test because a user on a FB group had perf issues with a 64bit Linux guest. After I suggested that he downgrade to 6.0.20, his perf is back to normal.

Which Linux distro/kernel version did you used for the host and for the guest?
How did you measure the performance problem?
