Practice question 375 of 506 · easy

A serial application is slow while total CPU is 20 percent on a many-core server. What should be examined?

Choose the single best answer.

  1. A.Only overall CPU idle percentage as proof no process is CPU-bound
  2. B.Per-processor and process CPU counters
  3. C.Only the server's total logical-processor count
  4. D.Only a longer-period total CPU average
Show the answer and explanation

✓ Correct answer

  • Per-processor and process CPU counters

Per-core and process counters can reveal a saturated serial execution path. A longer aggregate average can hide it, processor count does not show allocation/use, and overall idle capacity does not prove a serial process has spare execution capacity.
