" ...daca ai bani, esti fericit pentru ca iti permiti sa-ti traiesti viata asa cum doresti si iti cumperi libertatea. Daca n-ai bani, esti sclav care presteaza zilnic munca fortata, inghite umilinta de rigoare si traieste cu frica zilei de maine. N-ai cum sa fii fericit atat vreme cat nu iti poti satisface nici macar nevoile de baza, si esti obligat sa te vinzi pentru asta

.Exact ; banii sunt cei care fac diferenta intre libertate si sclavie, intre fericire si chin. Dar sarantocu' nu trebuie sa-si de aseama de asta, pentru ca il va apuca depresia ( si poate chiar revolta ) in momentul in care va intelege ca nu are scapare si va fi sclav pe viata, niciodata liber, niciodata fericit. Aici intervine propaganda cu spalare ade creier, si dreseaza prostimea ca fericirea e posibila si pentru sarantoci, ca fericirea e dupa colt, si trebuie sa te bucuri de lucrurile marunte :  ca rasare soarele, ca infloreste floricica, in timp tu presetezi munca fortata intreaga ta viata, ca ai primit 5 lei in plus la salariu, etc."

hyperthreading and the cpu usage

http://exadata-dba.blogspot.com/2014/01/system-performance-utilities-show-wrong.html

For CPU utilization less than 50%, multiply by 1.7.

∙ For CPU utilization over 50%, assume 85% plus (util-50%)* 0.3.

Here is a table that summarizes the effect: Measured Utilization	Actual Utilization
10%	17%
20%	34%
30%	51%
40%	68%
50%	85%
60%	88%
70%	91%
80%	94%
90%	97%
100%	100%

This information is applicable to all x86 abd x86-64 servers with HyperThreading enabled.

Enabling HT causes system statistics tools - vmstat, sar - show incorrect CPU load,
and Oracle performance tools - AWR, ASH - also show and store incorrect CPU load statistics.
