Anticipate Peak End User Load Reaction
Most systems are made with an end user mindset, and no user is willing to wait while the system dares to say still loading or this may take a while. The user has a limit. One of the possible repercussions of system overload is reduced functionality and speeds. With regular testing and upgrade retest including functional concurrency user testing on various platforms, you can tell how the system will respond.
For example, in web servers and websites, crash and error messages can further load the system beyond its capacity. Such system problems may require re-installation, something that may take long. Assuming you are selling live streaming access for a sporting event, an hour of system failure can mean complete loss of revenue. Only through in-depth analysis of the maximum loads and expected behavior can you truly be confident that you can remain functional.
Risk Allowance or Avoidance
Think of the run-time or the bottom line when referring to the functionality of servers, websites or other software, once they break down, that is revenue lost and cost escalated on the opposite direction. The system cannot stay down forever; you’ll need to rectify the problem sooner or later. A system crash can be fatal and may cause further damage.
Sufficient load and stress testing regimen before launch and continuously as per the upgrade demands can go a long way in knowing, anticipating and mitigating system limits.
Understand System Performance
Three things are important when it comes to performance. They are response time, throughput time and utility levels. If one of this is not happening and peak condition, system breakage is inevitable. How else would you test for the three metrics if not through data collection from continuous and remedial load testing?
Some developers make the mistake of thinking that system breaking point is always beyond the peak condition. This is not entirely accurate. System loads have been known to occur elsewhere apart from end user interface. Unresponsive scripts, system lag, hardware inefficiencies, intrusions, and malware, can all reduce the software, server, or websites optimal levels.
Once you know your system, you can stay on top of things when system performance goes below the expected levels. You can use a variety of tools to do this, and there are typically two categories: free and paid. Free tools would be something like Selenium, and paid tools would be something like LoadView.
Stay Hustle Free
Do continuous stress testing of the system especially before and after expected system overload. You will save yourself from spending man hours rectifying a system of diagnosing problems; your system will retain peak conditions, and you can stay hustle free.
