process tasks that cannot be completed in the physical memory.
Other adjustable items include keepalive, keepalivetimeout, and maxkeepaliverequests. Recommended settings that can be placed in the httpd. conf file include:

By reducing keepalivetimeout from 15 seconds to 2 seconds, you can add the maxclients command; 19 is too small, and 128 is much better. By reducing the number of seconds for a process to sur

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/
(If the figure is small, you can Ctrl + mouse wheel to zoom)Based on the last "Legend distributed server cluster concurrent landing on-line game test results" after the logical processing stress testing, still only configured a single gateway and a single logic service in the cluster, the results are as follows:Test Case:The first step: on-line 10,000 players, and then every 10 seconds for each player to se

Max_fails : The default number of times to allow requests to fail is 1. when the maximum number of times is exceeded, the return Proxy_next_upstream module-defined errorFail_timeout:max_fails The time of the pause after the failure. Backup: When all other non- backup machines are down or busy, request the backup machine. So the pressure on this machine is the lightest.

First you need to discover more information about gathering goals, including:
L The IP address of the host on the target network
L accessible TCP and UDP ports on the target system
L operating system used on the target system
Use Nmap for port scanning and system identification of the host, as shown in the figure:
You can see that the host is open for 80, 135, 139, 1025, 1107 ports, and 80 for the test IIS 6.0, the syst
1. The use of testing tools to simulate multiple end users concurrent testing;
The disadvantage of this test approach is that end users are often not directly connected to the database, but rather pass through one or more intermediary services, so it is not guaranteed to access the database or concurrency. Second, this test method needs to wait until the client program, the

SYN requests implement pressure monitoring using TCP protocol defects and send a large number of forged TCP connection requests, so that the attacked party's resources are exhausted and cannot respond to or process normal service requests in a timely manner. A normal TCP connection requires three handshakes. First, the client sends a packet containing the SYN sign, and the server returns a SYN/ack response packet, indicating that the client request is

In the following sections of this column, we describe in detail the scripts used to create the virtual machines shown in Figure 1, as well as the scripts used to set up and execute test automation. We believe you will find that the technology we are introducing here is a useful complement to your software testing, development, and management skills.
