Transfer data from stdin over network to destination quickly
fling transfers data quickly over a trusted network. It does not encrypt the data. It tries to avoid copying data between kernel and userspace where it can. The most improvement over other tools like netcat is seen on systems with low memory bandwidth. fling is extremely Linux-specific, as almost all the optimisations used beyond what other similar tools do are non-portable.
