When a set of programs is finished or a server configuration is complete, many friends will be like me, I would like to know how much load pressure it can withstand, that in this article, we will introduce 10 free web-based load/stress testing tools, so, You can see how much concurrency your server and your Web app can hold, and the performance of your site.Grinder –grinder is an open-source JVM load test f

This article lists 10 free tools that can be used for Web load/stress testing. This way you can see how much concurrency your server and your Web app can handle, and what the site does.0. Grinder –grinder is an open-source JVM load test framework that facilitates distributed testing with many load syringes. The Jython scripting engine HTTP tests that support the execution of

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

In XEN/KVM virtualization, CPU, memory, and network I/O are generally more efficient in virtualization, and disk I/O virtualization is inefficient, so the disk can be a bottleneck. In general, the database has high disk I/O requirements, and can measure the performance of running MySQL, Oracle, and other database services on the client (although I know that it is also more efficient to run the database server in the client). This article does not describe the performance of MySQL in virtual mach

Apache JMeter is a Java-based stress testing tool developed by the Apache organization. For stress testing of software, it was originally designed for Web application testing but later extended to other test areas. It can be used to test static and dynamic resources such as static files, Java applets, CGI scripts, Java

AB's full name is Apache Bench, which is Apache's own network stress test tool, which is the simplest and most versatile of the Http stress testing tools I know compared to LR and JMeter.The AB command is very low on the computer that emits the load, does not consume very high CPU and memory, but can also generate a huge load on the target server, which can achie

Objective: To carry out stress tests on the set of providers and consumers of micro-service to find out possible problems and ways to solve them. Create a client project (feign) that provides the HTTP interface to the JMeter call, which uses the feign client to request a micro service on another machine: JMeter--> Client (feign, Hystrix)--> Micro Service (User-service) Code on the client: @RestController public class Usercontroller { protected final

First, Http_loadThe program is very small, after decompression is less than 100KThe http_load runs in parallel multiplexing to test the throughput and load of the Web server. However, unlike most stress testing tools, it can run in a single process and generally does not kill the client. You can also test site requests for HTTPS classes.: http://soft.vpser.net/

In operation and maintenance work, stress testing is a very important work. For example, before a website online, can withstand how much traffic, in the case of large traffic performance, these data indicators will directly affect the user experience. However, in the stress test there is a common denominator, that is, the results of the
