best pc performance test

People who have some experience in performance testing are easy to get into this state, they are already familiar with the basic process of performance testing and are able to work with the test tools more skillfully. I was probably in the performance test about a year or so

Analysis principles:• Specific Problem Analysis (this is due to different application systems, different testing purposes, and different performance concerns)• Locate bottlenecks in the following order, from easy to difficult.Server hardware bottleneck-> network bottleneck (for LAN, you can ignore it)-> Server Operating System Bottleneck (parameter configuration)-> middleware bottleneck (parameter configuration, database, web server, etc) -> applicati

For more information about the series of directories, see. This section mainly solves three problems: finding the external rectangle of any geometric image. This external rectangle will be used in performance optimization. Of course, it is not only used in this aspect. Finally, the pressure

Before you start About this series Writing code for an application is only the first phase of the lengthy process required to deliver a robust product quality program. The code must be tested to verify its operation and accuracy. It is also often necessary to analyze the code to eliminate performance bottlenecks and resource waste (especially memory). Code must also be monitored to locate faults, identify usage patterns, look for opportunities for f
