Which is completely irrelevant. I'm not comparing it to something
else (although if you want me to do that, I'll note that my Ultra 60
running SXCE was faster at packaging that the modern core 2 laptop
running OpenSolaris that I used recently). The point is that with identical
configurations on the same hardware, pkg(5) is much slower than SVR4.

Come now. I've installed the system and left it untuned.

But that *is* the comparison of interest.

Pkg(5) has had considerable development effort expended on it. It's been
released in shipping product for over a year. SVR4 has been neglected and
left to rot.

Are you willing to accept that pkg(5) does have serious problems
with performance, and needs improvements of an order of magnitude
or more?
