I didn't know that time(1) didn't accumulate user and sys. Thanks
for that.

Ok, I've since updated both build boxes with the 20090419 snap and
have used a simpler test case of gzcat comp45.tgz | wc. Without the
pipe, I was unable to stimulate the condition that resulted in the
performance degradation.
The new testing adds more wrinkles... The i386 and amd64 platforms
behave differently than expected, ie. I was expecting both platforms
to show the dramatic degradation noticed with the "make" test.
However, only the 2-core i386 showed significant degradation. The
4-core amd64 platform showed much less degradation with -current.
In the following mini-analysis, time(1) is used as the measuring
stick. "4.5" refers to the 4.5 release as found on the official CD.
"snap" refers to the 20090419 -current snapshot. "baseline" means
no niced processes. "niced busy" means one busy process per core.
"x4" refers to an AMD Phenom 9550 quad-core processor on an ASUS
M3A78-EM motherboard. "v1" refers to an AMD Athlon X2 dual-core
processor on an ASUS M2N-E motherboard. dmesgs are appended for
both x4 and v1 running the forementioned "snap". dmesgs for the
"4.5" cases are in my previous message.
"baseline" shows no significant difference between "4.5" and "snap"
on either the v1 or x4 platforms.
"niced busy" on x4 with "4.5" shows little significant difference
with the "baseline" (If anything, the numbers are unexpectedly
slightly better). The additional niced processes apparently don't
offer enough perturbation perhaps due to 4 cores available instead
of 2 with v1.
"niced busy" on x4 with "snap" shows more than 3 seconds increase in
real time. This is much less dramatic than the same test case with
v1.
"niced busy" on v1 with "4.5" shows appx. 4 second increase in real
(elapsed) time while the user and system time are appx. the same.
The additional niced processes probably prevent overlapping the
gzcat and wc processes thus resulting in the increased elapsed time.
"niced busy" on v1 with "snap" shows more than 150 seconds increase
in real time. Interestingly enough, the user and system time are
more variable and less than the "baseline" results. I can't explain
the results of this test.
I've appended the gory details which include "dnetc" results as
described in my previous message. The "dnetc" results are similar
to "niced busy" and are only included for completeness.

That sounds like fertile ground to explain the observations.

I realize the niced processes still have an effect on performance.
However, with 4.5 release and earlier, it was seemingly
insignificant. However, there is now a quite noticeable performance
reduction while building ports. FWIW, I have noticed additional
sluggishness in the past few months but am unable to quantify with
reproducible results and haven't reported.

You're exactly right about dnetc switching to nice 20 while my busy
scripting defaulted to 10. When I reran the tests for the new gzcat
test case, I tried both 10 and 20 and didn't observe any difference.
