gradually widens as the number of conditions increasesFor character variables, if-then/else statements is always more efficient than SELECT STA Tements. The performance gap widens quickly between the techniques as the number of conditions increases.Best case scenario with two optionsUse If-then/else statements when?? 1:the data values are character values?? 2:the data values is not uniformly distributed?? 3:there is few conditions to check.Use SELECT statements when?? 1:you has a long seri

OBS is an open source coded push-flow tool that is easy to use and very popular.In one project, it was found that 32-bit OBS streaming CPU utilization was 100% under this desktop I3 processor.

Discard the use of Wayland and switch to x Window

Optical Crossover Connector (OXC) and optical divider (OADM) are used to complete the switching function ). After several years of research and experiments, all-optical networks are now developing in an intelligent direction. Automatic Switching Optical Networks (ASON) is the mainstream direction for intelligent development.
Strictly speaking, wave splitting switching is different from wavelength routing. Wavelength converter is required for wavelength division switching networks, while wavelen
connection persistence time is relatively short, it will cause the channel utilization to deteriorate. Therefore, it is not suitable for continuously increasing and changing Internet traffic, such as web browsing, FTP file transmission, and email.In optical switching, OPS provides better bandwidth utilization, latency, and adaptability. In the long run, OPS seems to be a promising technology, but its implementation is complicated and the current optical logic processing technology is not mature
