JMeter stress testing Overall goal: Install the virtual machine, and install a LAMP (Linux + Apache + Mysql + PHP) to test the system, we recommend ECShop (http://www.ecshop.com), based on this Jmeter pressure test, the Jmeter test report is obtained after the test, and the CIMN (CPU, IO, Memory, and Network) performance of the Linux server is obtained based on sysstat. Division of labor: Role 1: Install

Ideas: The stress testing, SQL optimization, memcached optimization, SQL stress testing, and other simulated samples are tested to form a series of methods to prepare our knowledge reserves for possible future situations. Of course, at present, our small systems do not need such optimization, but may only be improved b

user may produce multiple sessions at the same time, the number of connections. Under http/1.1, IE7 supports two concurrent connections, IE8 supports 6 concurrent connections, and FIREFOX3 supports 4 concurrent connections, so we have to divide the number of concurrent users by this cardinality accordingly. 4: Average user request wait time (times per request) Calculation formula: The amount of time spent processing all requests (total requests/concurrent users), i.e. Time to request = time

AB is a stress testing tool that comes with Apache and can be used for simple stress testing on interfaces. The following is a brief introduction of AB. Format: AB [Options] [http: //] hostname [: Port]/path parameter description: -N requests number of requests to perform // number of requests executed in the test ses

Doing API-related work is challenging, and keeping the system stable and robust at peak times is one of the reasons why we do a lot of stress tests in Mailgun. For so long, we've tried a variety of ways, from simple apachebench to more sophisticated custom test kits. But this post is a way to use Python for "fast rough" and very flexible stress testing.When using Python to write HTTP clients, we all like t

AB is a very easy-to-use stress testing tool. It does not need to be installed in linux. Here are several key parameters of AB and examples of use.Requests per second: the number of Requests per second. This is an important parameter value, indicating the server throughput.Time per request: average user request wait TimeTime per request: average server processing Time, that is, the reciprocal of server thro

Because a server (server a) is powered off by an IDC without reason and the root directory of the file cannot be written, you need to switch the data and services running on this server to another server (server B) in order to stop the business on a for repair. Before data migration, You need to perform a stress test on the database on B to see if the existing and additional database throughput can be taken into account simultaneously. I have read the
