CPU utilization on DL580
Hi,
I am using OEL 5.3 64-bit on HP DL580 (4 CPU). i am decompressing the Oracle backup by tar command.
only one core is being utilized 65% and rest of the cores are free and load average is 4.4.
I want to know why the CPU is not being equally utilized?

Re: CPU utilization on DL580
Because gunzip isn't multithreaded. And I assume the gzip format doesn't lend itself to parallel processing.
Do something else with those CPUs.
