APP STARTUP TIME MANUAL

Monitoring Application Startup the uberAgent Way It is a good method for evaluating the effects of configuration changes on the performance of the entire system, but not more. This, too, tells you how the machines are performing you are running the script on.

Another approach is to simulate user behavior in real applications with scripts.

This tells you something about the machine’s performance in general, but it does not tell you anything about the applications your users are running.

One construct relies on regularly launching a specifically instrumented monitoring executable.In practice, it turns out many do not observe what is but create their own alternate reality instead. Several vendors claim their products monitor application startup performance. How not to Monitor Application Startup Duration We can also estimate how dependent a process’s startup performance is on disk speed. If we have the IOPS in addition to the startup duration we can gauge the strain a process launch puts on the disk subsystem. Therefore, when monitoring process startup duration, the generated IOPS should be kept in mind, too. In other words: process startup duration is heavily dependent on the machine’s IO performance. Part of a process’ startup duration is spent waiting for the disk to read all these DLLs. The longer that takes, the more sluggish the system feels. These child processes need time to start up, too, of course.

But process creation is not limited to manual intervention Windows runs dozens of services in the background, many of which regularly create child processes. When you start an application, Windows creates a new process for you. Under the hood, applications consist of one or more processes.

Each of these DLLs is initialized in turn which adds a lot to the application’s overall startup duration. Additionally, all applications use additional logic outsourced into DLLs, most of which are loaded during application startup, too. This is because applications need to perform all kinds of initializations before they are ready to show their UI and interact with the user. Whenever you click an application’s icon, you wait. That, however, is not exactly easy – without uberAgent for Splunk. If you want to make sure that UX on your Windows machines is acceptable you need to monitor the time it takes for applications to start up. Application startup duration is an essential component of user experience.
