Hi,

I reckon it should be played slowly, slip jigs tend to be slower than jigs.

If you treat each group of 3 quavers as being equal to a crotchet, it would be about the right speed for a waltz. (It's a pretty laid-back butterfly!)

There is a great arrangement of it on "Celtic Odyssey" (ND-63912 from Narada), where it is played in 3 different time signatures by a group called Orison (apparently a group from San Francisco.)
