--- Comment #4 from rkoberman at gmail.com ---
I'm seeing something similar and have been seeing it on 13 since it was
13-current. Doing a "make extract" before and after building www/firefox takes
many, many minutes. 

The system is a ThinkPad L15, but my file system is SU, not SU+J. When I
monitor disc usage, it is inconsistent. It runs at "normal throughput of
>40MB/s. It will abruptly drop to <2MB/s and remain there for a time that
varies from a few seconds to minutes. It then jumps to normal throughput. This
a spinning rust, so TRIM should not be involved. Since 12.2 does not support my
graphics (CometLake), I really can't compare to 12.2. Also, I am running
13-STABLE, not BETA4. It was update on the 27th, shortly after BETA4 was
announced, so I assume I have all BETA4 fixes. Disk performance monitored with
gkrellm2.
