What is Performance Tuning?
1-4 Oracle HTTP Server powered by Apache Performance Guide
In parallel processing with multiple resources, more resources are available to the
tasks. Each independent task executes immediately using its own resource: no wait
time is involved.
System Throughput
System throughput is the amount of work accomplished in a given amount of time.
You can increase throughput by:
■
Reducing service time
■
Reducing overall response time by increasing the amount of scarce resources
available. For example, if the system is CPU bound, and you can add more
CPUs.
Wait Time
While the service time for a task may stay the same, wait time will lengthen with
increased contention. If many users are waiting for a service that takes one second,
the tenth user must wait 9 seconds.
Figure 1–2 shows the relationship between wait
time and resource contention.
