PHP archive phar performance test PHP has added PHAR archive since 5.3. The concept of Phar archive comes from Java? Technical JAR archive, which allows you to use a single file to package an application. This file contains everything required to run the application.

Http://www.aikaiyuan.com/5318.htmlThe most common tool for Web services to do performance load testing is the Apache benchmark commonly known as AB and Commercial tool LoadRunner. AB Simple direct, the function is also relatively weak, but we often see some of the Web server or the framework of performance testing with AB, and the LoadRunner function is indeed very powerful, a variety of large software com

, but also the consumption of other functions called by this function.Xhgui Another feature is "Call graph" (callgraph), "Call graph" in vivid virtual way to show how time is consumed:This is a good demonstration of the hierarchy of function calls. The best thing is that the graph is interactive and you can drag and drop to better see the connection; You can also swipe over the "circle" (BLOB) to see more information. When you interact with it, it's fun to bounce back and move, which is not a ve

Memcached and Redis Performance test summary– The same data model, memcached can save more heat data than redis, such as memcached in 13G of limited memory can save 100 million data, and Redis probably saved 80 million– the same server environment, memcached write performance is higher than Redis, the former about 100,000 per second, the latter about 70,000 secon

In the Taobao environment, assuming that we stress test the TPS is 100, then the system's daily throughput =100*11*3600=396 million This is in the case of simple (single URL), some pages, a page has multiple request, the actual throughput of the system is also small Regardless of time-to-think (T_think), there is a relationship between the measured TPS value and the number of concurrent virtual users (u_concurrent) and the transaction response time

The Requests/second in the performance pressure test responds to the Spike problem, requestssecond Recently, I have been busy with the final sprint of switching to the java project. The coding code, debug, and fixbug in the early stage are all gradually closed, and the performance pressure test before going online. Alt
