Is it feasible to maximize all computer resources for every task?

In batch processing situations, you might get one resource fully utilized while others are less active, since there's often a bottleneck somewhere. Proper planning should ideally ensure that the bottleneck is the most costly resource, but get it wrong, and you end up wasting expensive hardware. In terms of unpredictable workloads, you don’t want to be constantly maxed out; retaining some headroom is crucial.

We often rely on autoscaling to meet demand without wasting resources. Very few workloads maintain a constant demand, so it's wise to plan for fluctuations. Running at full capacity all the time is generally not advisable.

It really depends on the workload, but aiming for high utilization is common in data centers. User-facing applications can be trickier due to variable traffic, making high utilization a challenge. Overall, it's a reasonable expectation, but context matters.

Maximizing computer usage isn't always the best approach, especially with concerns like climate change and energy efficiency. Good software minimizes unnecessary power usage. Plus, consider real-life scenarios; you don’t use every kitchen tool while cooking. Just because you have the capability doesn't mean you should always use it to the max.

While we always aim to make the best use of available resources, there are limitations based on the software's design. For example, multithreading can boost efficiency, but not all applications support it yet. Sometimes, the person asking just doesn't grasp the complexity involved or might be facing a unique issue that’s better handled differently.
