Software Performance Engineering is the systematic approach to constructing software that meets performance objectives. It is more related to building a tuned software application at the early stage of the software development life cycle whose performance satisfies all the non-functional requirements during the performance testing phase. On the other hand, Software Performance Testing is the act of evaluating the software system … Read more
Linux server performance monitoring through the ‘ss’ command provides the monitoring statistics related to network sockets and connections. ‘ss’ stands for ‘Socket Statistics’ and it is a simpler and faster version of the obsolete command ‘netstat’. ‘ss’ utility completely replaces ‘netstat’ in the Linux Performance Monitoring system which provides more advanced features and flexibility. It has … Read more
Linux server performance monitoring through the ‘iostat’ command provides general information about disk operations and related statistics. ‘iostat’ stands for ‘Input/Output Statistics’ and it is a utility that monitors system input/output by observing the time the devices are active in relation to their average read and write rates. The output of the command ‘iostat’ helps … Read more
Linux server performance monitoring through the ‘mpstat’ command, is one of the oldest and most valuable ways to capture CPU statistics. If the system is a multi-core processor, then the mpstat command helps monitor each core CPU. If a Linux kernel has dual processors with dual cores, the command will report 4 CPUs statistics. The … Read more
Linux server performance monitoring through the ‘vmstat’ command, is one of the oldest and most valuable ways to capture memory statistics. ‘vmstat’ stands for ‘Virtual Memory Statistics’ and it is a utility that provides an excellent low-overhead view of system performance. Because ‘vmstat’ is such a low-overhead tool, it is practical to keep it running … Read more
VMWare systems are used as servers to provide virtualization solutions for businesses. Virtualization is a technology used to allow a single physical server to be divided into multiple virtual servers, each running its own operating system and applications. This provides a great deal of flexibility, allowing businesses to deploy applications quickly and easily while reducing … Read more
