Hi again,

I have been investigating about this and I think that with top I don´t get
the usage of the cpu but I get de % of the cpu of the process.

I´ll explain better with and example.

With the command sar I get that the cpu usage es 35%, for example,
and with top I get that java is using 80% but what it is saying that the
java process is using the 80% of the 35% of the cpu usage, not the 80% of
the whole cpu.

Do you think that my conclusion is true?

BTW, is there any parameter in the system that tells the kernel the limit of
cpu a process can get?
