As an important part of the software as a service (SaaS), several cloud service providers have also offered stress testing and performance monitoring services.Bucket Principle Based System Optimization The bucket principle, also known as the short board theory, describes the core idea that the amount of water a bucket can hold does not depend on the highest board, but on the shortest piece of board.
Rpc.Rstatd And Rpc.Rusersd Software As AWhen the bucket principle is applied to s ystem analysis, it means that the final performance of a system depends on the worst-performing components in the system. To improve the overall system performance, the worst performing parts need to be optimized to achieve the best results. In the website system, when a users access request reaches the server, the data is returned and displayed back to the user. Inefficiency in any process will affect the overall system performance. According to the bucket principle, if the performance of a server is very powerful with sufficient memory and Central Processing Unit (CPU) resources, but has insufficient disk InputOutput (IO), then the overall performance of a system is determined by the current slowest disk IO speed instead of the current most superior CPU or memory. One of the common examples is systems using Redis for storage. Redis has excellent performance and, often, the storage does not restrict system performance. However, with large requests, Redis throughput is vast, and the network bandwidth becomes a bottleneck in the system. It is usually combined with capacity estimation and other tasks and interspersed with different plans in system development. Performance testing can help us discover the system performance short board, evaluate the systems capability, and carry out targeted optimization. Meanwhile, stress testing can also help verify the stability and reliability of the system. A performance test plan usually includes the following components: 1. Rpc.Rstatd And Rpc.Rusersd How To Generate StressStress Testing and Performance Report Generation One focus of stress testing is how to generate stress. This can be achieved by writing scripts to simulate requests or by using sophisticated stress tools. In stress testing, it is important to use realistic data that is as close to real-world users as possible. Identifying System Bottleneck The stress test report usually shows data like query per second (QPS), transactions per second (TPS), response delay, etc. This data allows us to understand the servers performance and to identify existing problems, but it cannot help us pinpoint the problem. This is when we need to look into the various system components, compare the impact of CPU, memory, IO and network on the overall performance, determine which part affects system performance, and conduct optimization individually. Estimating Load-carrying Capacity One principal purpose of stress testing is to get the most out of the existing server resources. The early testing and analysis have provided us with an understanding of the systems overall performance and an estimation of the systems load-carrying capacity. It is now time to configure the number of servers and CDN resources, depending on the business scale so that we can get the greatest value out of the fewest resources. Selection of Common Stress Testing Tools One focus of stress testing is how to generate stress. Large internet companies such as Google, Alibaba and Baidu all have specialized test development teams that are responsible for developing testing tools to better cater to the enterprises business.
