Depending on the time and resource characteristics of the product, the efficiency test can include different types of tests, such as performance tests (performance test), load tests (loading test), and stress tests (Stress test). These three types of efficiency t
Performance testing, load testing, stress testing What's the difference? Performance testing (or antisymmetric user concurrency performance testing), load testing, strength testing, and capacity testing are some of the areas of performance testing, but concepts can easily be confused. Here are a few concepts to introduce.

IntroducedWhen any software development project is nearing completion, it may have passed numerous tests, especially in the context of testing and development of simultaneous agile testing. No matter how many rounds of testing you have, once your application is nearing completion, there is only one way to know if your software can meet the real needs of the real user base, which is the load test. You can us

Oracle RAC Load Balancing enables client-initiated connections to be efficiently allocated to instances with smaller listener loads. There are two ways to achieve client load balancing, one is by configuring the client's load_balance, one by configuring the server-side Remote_listener parameters. Both approaches have advantages and disadvantages, and they are not mutually exclusive, so they can be combined
time slice interruption of the process. (In Linux 2.6, the system clock interrupts the clock frequency every 1 milliseconds, expressed in HZ macro, defined as 1000, that is, 1000 interrupts per second.) System is not the same, the kernel is not the same configuration 100, 250 have. )
The clock frequency of the kernel can be known by the following command
cat/boot/config-' Uname-r ' | grep ' ^config_hz= '
config_hz=100
The total number of clock interrupts per second is = number of CPUs * Number
wondering whether two users can accurately reflect the compression capability of your program. Of course you can use standard test methods (publish your program and expect the best results), yet you decide to test your program's performance in advance. That's a good sign!

Program | Server server load is too heavy to affect the efficiency of the program is also very common, we need to test this. Here I take the current most common Apache server as an example.
The Apache server comes with a tool called AB (Apachebench), which is in the bin directory. Using this lightweight tool we can load test

Website loading speed is the most important factor to determine the level of the site, worthy of special attention of stationmaster. The reason is simple, no one wants to open a Web page and so on long time, in other words, if your site is very slow to open, will churn out a large number of visitors, and even the effects of the multi-meter effect of the adverse effect. Before you dive into the code to try to improve your site's speed, determine what the real cause of the slow site access is. Thi

ASP optimization: Load Test Your ASP programIntroducedAs we move from the traditional CS-structured application to the current popular web-space program, we find ourselves trying to keep up with growing testability requirements and performance requirements. One of the biggest challenges is how to determine how many users your program can support. How do you face this challenge? Setting clear performance goa
