13. Web Stress Test-httperfHttperf is more powerful than AB and can test the maximum number of services a Web service can carry and identify potential problems, such as memory usage and stability. Maximum advantage: You can specify a regular pressure test to simulate the real environment.Download: http://code.google.com/p/httperf/downloads/list [Email protected] ~]# tar zxvf httperf-0.9.0.tar.gz [Email protected] ~]# CD httperf-0.9.

Prot_none indicates that the process does not have any of the above 3 access rights. flag: This parameter specifies additional flags for the virtual area. The function calls the Do_mmap_pgoff () function, which does the main work of memory mapping, the function is longer, detailed implementation can be viewed Since the mapping of the file to

Hands-on practice of Linux VLAN-playing with OpenStack (13) every five minutes) This section describes how to implement and configure the following VLAN network in the experiment environment.

Restart the host machine, ifconfig Network In

) cannot have two VLAN sub-devices of the same ID, so there is no possibility of data exchange. Linux Bridge is designed for switching functions. The sub-devices of the same VLAN are mounted on a Bridge, and data can be exchanged between devices. In summary, Linux Bridge plus VLAN emulates the real-world two-layer switch at the functional level.The eth0 is equivalent to the trunk port on the virtual swit

shared by multiple devices.const char * devname device NameVOID*DEV_ID used when sharing interrupts.The main difference between a fast/slow interrupt is that a fast interrupt guarantees the atomicity of the interrupt processing (not interrupted), while a slow interrupt is not guaranteed. In other words, the "on interrupt" flag bit (processor if) is turned off when the fast-breaking handler is run, so when the service is interrupted it is not interrupted by other types of interrupts, while the o
