Item and Fluid pipes have a moderate transfer rate by default, which should be enough for most uses. However, if you need to transport a lot of items or fluids very fast, a pipe booster block can be attached to a pipe. When it is powered, it will massively increase the operation speed of the pipe behind it. Item pipes will extract a stack every tick, and fluid pipes will extract up to 40 buckets per tick.
Heads up!
The booster needs to target an extracting pipe block. So it must directly target the block where the pipes interface with the machines.
