My point was that the filter was being recursed via a pipeline. In fact, if I understand things correctly ... the filter method should have pretty much the same overhead as the function, plus the overhead of running that mini pipeline? Yes, yes … functions and filters are the same thing … that wasn’t my point. My point was that the filter was being recursed via a pipeline.

Is the delay explained as simply as:

function – filter = parameter binding

?

In fact, function and filter are just syntactical sugar for the same. These two definitions are the same: function test1{ process { $_ } } filter test2{ $_ } Try to do a type function:test2 and see the output. Best regards Per www.msgoodies.com Hi

In particular, function overhead is very heavy in V1 but we are working on improving this in V2. We did very little work on performance in V1.
