RoadRunner is an open-source application server, load-balancer and process manager written in Golang (Go) and implemented by PHP 7. It is used in rapid application development to speed up the performance of large web applications for users.
The effect on application performance of opcode caching varies widely, depending on factors such as the inherent execution time of the PHP application and the percentage of source code actually executed on a given request, and whether additional optimization steps are performed.
An automatic optimizer (or optimizing compiler, a program that performs code optimization) may itself have to be optimized, either to further improve the efficiency of its target programs or else speed up its own operation. A compilation performed with optimization "turned on" usually takes longer, although this is usually only a problem when ...
Load balancing can optimize response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle. Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic ...
allowSmall – whether a small version of the message box can be produced with "small=yes". smallParam – a custom name for the small parameter. For example, if set to "left" you can produce a small message box using "small=left". smallClass – the class to use for small message boxes. substCheck – whether to perform a subst check or not.
This Lua module is used in system messages, and on approximately 10,300,000 pages, or roughly 17% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox .
The code-rate is hence a real number. A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.
I/O completion port loops run separately from the Message loop, and do not interact with the Message loop out of the box. The "heart" of most Win32 applications is the WinMain() function, which calls GetMessage() in a loop. GetMessage() blocks until a message, or "event", is received (with function PeekMessage() as a non
