Ani jsem netusil, ze VirtualBox neco takoveho umi, takze jsem zase o
neco chytrejsi. No u me to vypada, ze kdyz mu pridelim 6 jader, tak i
guest vidi 6 jader. Zkusim to ted rebootovat a zvednout to na 10 a
pozorne si prohlidnout, jestli jich je skutecne 10.
Opravdu system vidi 10 jader
FreeBSD/SMP: 1 package(s) x 10 core(s)
Problem je, ze je s temi 10 jadry opravdu neuveritelne pomaly. Takhle to
vypadalo ctvrt hodiny po rebootu (v noci, kdy je na serveru minimalni
provoz a zatez by mela byt okolo 10% / load 1)

Porovnaval jsem nastaveni virtualu s tim, co poslal Dan a krome
vypnuteho PAE tam byly ty podstatne veci stejne. Tak jsem zkusil zapnout
PAE, ale zadny rozdil v tom chovani nepozoruji.
