For starters, the original poster is using AMD64, so whether an
ultrasparc improves thread performance is immaterial here.
OP said:
"Solaris 10 x86_64 with postgres 8.3.8 and openssl 98k using gcc version
3.4.3"
Although the article is interesting, the data came from (or passed
through) Sun employees. I'm not saying the article's claims are not
true or intentionally misleading, but rather that I am skeptical about
the findings; especially since it reads more like a marketing piece than
a technical analysis.
BTW, I have nothing against Sun or Solaris (spent a few years on Solaris
7 & 8 sparc servers a while back and found them quite stable). I'm just
a hard sell do to endless exaggerated claims by all the top vendors and
techy outlets. I find myself weeding through all the hype with a machete :)
