What is a rule of thumb for the average load for a single UNIX-based server before optimizing performance or scaling? For example, my server is running as shown:
load average: 0.44, 0.44, 0.43

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

Load is the number of processes waiting to run on the CPU. If it's below the number of CPUs available on that system, that means that, on average, you don't have any processes waiting. A more complete answer is here. | |||

This question can't be answered on a general basis. One example: A load average of 0.4 means something different with a single core system than with a 16 core machine, and it can also mean that your CPU is idling while processes wait for I/O on some OSes (i.e. Linux). Do you experience any performance problems? Do you expect any increase in load? | |||
