The difference between ET and LT pattern in Epoll

Epoll operates on a file descriptor in two modes: LT (Level Trigger, levels trigger) mode and ET (Edge Trigger, Edge trigger) mode. The LT mode is the default operating mode, which epoll equivalent to an efficient poll. When registering the Epollet event in the Kernel event table in Epoll, Epoll will manipulate the file descriptor in the ET mode. ET is an efficient mode of epoll. For file descriptors that

Comparison of SELECT, poll, Epoll for Linux network programming, and Epoll horizontal trigger (LT) and Edge Trigger (ET)

question, Epoll sets up a list of ready lists separately, when FD is ready (readable/writable) and placed in the Ready list. Epoll_wait only needs to traverse the ready list, without having to traverse all of the FD, thus saving a lot of CPU time.Epoll has LT and et two operating modes, the default operating mode is LT (horizontal trigger), high-speed operation mode is ET (Edge trigger).It is an FD that no

Some concepts and distinctions of time (UTC, GMT, LT, Tai, etc.)

"seconds",The computational process is fairly rigorous, so UTC is more accurate than GMT in terms of "world standard Time".The error value must remain within 0.9 seconds, and if greater than 0.9 seconds is released by the International Earth Rotation transaction NCBs in Paris, the UTC will be the same as the Earth rotation cycle.So essentially the nature of UTC emphasizes a more precise world time standard than GMT. It's actually a more precise GMT. LT
