Decelerator

From fmepedia

Slows down the flow of features through the FME.

The slowdown amount may be specified as either a delay per feature, in which case each feature will be delayed by the number of seconds specified, or by a maximum number of features per second, in which case the transformer will ensure that no more than that number of features are output each second (though no guarantee is made that any pair of sequential features will have the same time gap between them).

This transformer is commonly used in conjunction with the HTTPFetcher to slow down web requests and avoid overwhelming the target server.

FME Function Used: @Tcl2 (after)
