| I didn't fully grasp the difference between self-reducible collections v.s. other ones (in this context, and in general). Can you please delineate?
I think this means that collections which implement CollReduce have an implementation of reduce which is faster than just calling first and next on them. Transducers will use this implementation when available. This is one of the biggest speedup of transducers over seq, which always use first and next to iterate. That said, if the collection does not offer a faster CollReduce implementation, it will fallback to using first and next, and thus won't be faster than sequences. | Roughly how much performance lag do we get when not working a transduction from a (self) reducible collection, and moreso why exactly? I covered why above, but I do not know how much performance lag there is. It would depend on the concrete collection and how faster its CollReduce implementation is over using first and next. | Should we typically choose a different vehicle for stream processing from large files, over using transducers? My current use case is stream-processing from large files. I think as a stream, you won't benefit from CollReduce, but I'm not sure. I don't think you can really reduce over the stream faster than first and next. That said, you might benefit from loop fusion if your operations can be fused.
