lzo2 shows insane speed gap

Sure.  Let's cut this short:

"Slow"
Athlon 64 X2 5200+ 2.6 GHz,          FreeBSD 8.0-CURRENT amd64   ~60 min
Phenom 9350e 2.0 GHz,                OpenBSD 4.4-CURRENT amd64   ~80 min
UltraSPARC-IIe 500 MHz (Blade 100),  OpenBSD 4.4-CURRENT sparc64  10 h++

"Fast"
Pentium 4 3.0 GHz,                   FreeBSD 6.4-RELEASE i386     36 s
Xeon E5405 2.0 GHz (PowerEdge 1950), OpenBSD 4.4-CURRENT amd64    47 s
Alpha 21164A 500 MHz (AlphaPC164),   OpenBSD 4.4-CURRENT alpha     9 min

Let me draw your attention to the fact that the two amd64 systems
that run different operating systems are both slow, whereas the two
amd64 systems that run the same operating system (compiler, libraries)
diverge in speed.


Oh, and everybody is invited to run

$ cd /usr/ports/archivers/lzo2 && make

and check for themselves.


PS: The Blade 100 is still crunching as I write this...
