CI Framework Source Reading Note 5 Benchmark test benchmark.php
Since benchmark is the first core component to be loaded in CI, our analysis begins with that component first. The meaning of benchmark is very clear, the students who have used the benchmark tool should be more clear, this is a
Previous blog (CI framework source reading Note 4 boot file codeigniter.php), we have seen: CI in the core process of the core functions are done by different components. These components are similar to a single module, different modules to complete different functions, the modules can be called each other, together constitute the core skeleton of CI.From the beginning, will be further analysis of the implementation of the details of the components, in-depth CI core black box inside (after the s

Sysbench Introduction
Sysbench is a modular, cross-platform, multithreaded benchmarking tool that is used to assess the load of databases under various system parameters. It mainly includes the following methods of testing: CPU Performance Disk IO Performance Scheduler performance memory allocation and transmission speed POSIX thread performance database performance (OLTP benchmark)
At present, the Sysbench mainly support mysql,pgsql,oracle 3 kinds o

Running software such as antu can help mobile users understand the performance of their mobile phones. This function meets the needs of most people, so antu is popular. Of course, there are more than one running software on the market. These running software are similar. The basic principle is to test CPU and GPU by simulating user operations (such as playing games, computing, and listening to music, MEM

Benchmarking is a stress test for system design. The goal is to master the performance of the system, or to reproduce a system state, or to perform reliability testing of new hardware.1 Why do benchmark testsBenchmarking is the only convenient and effective way to understand what happens to a system under a given workload. Benchmark tests can hang the system's behavior at different pressures, evaluate the s

Redis takes a tool called Redis-benchmark to simulate N clients and send m requests at the same time. The experiment was carried out as the following comparison test:(1) in the quiet mode and the explicit use of the command to run the comparison;(2) Contrast in single key and random key mode;(3) Compare the default 50 clients, 100 clients and 10 clients;(4) In order to

No matter what kind of system you implement, you may have considered a series of questions like this:
What kind of equipment should I buy?
How is my system performing?
How many users can my system withstand?
How much concurrency can my system endure?
When will the perfor
