CPU reporting incorrect values

[fred974]

Hi,

Could anyone please help me understand wich value I should go by when looking at CPU resources?
XOA:

XO Lite:

Server htop

According to Xen Orchestra, I am using almost all of my 8GB RAM where as in htop, I am only using 1.74G.

Which one should I trust?

Thank you

Hi,

Check carefully your htop output. See the huge yellow bar? That's the buffer/cache used

edit: also please fix the title, your request is related to memory, not CPU
