FreeBSD 13.0-BETA2 and slow IO

[Christos Chatzaras]

I build a test system with 13.0-BETA2 and it's very slow with at least IO.

Doing "portsnap auto" takes much more time than 12.2.

Also when I do "rm -fr /usr/ports" with 12.2 takes 5 seconds and the same command with 13.0-BETA2 takes 100 seconds.

The disks are similar 4TB HDD drives on both systems.

Is this related to debug enabled in 13.0-BETA2?
