I think it should not be used with WB 3.5 or better because SetPatch does the work that BlizKick used to.
Not really. It's actually better to use BlizKick to apply patches from OS3.5+ instead of SetPatch because you can save a reboot at cold start.
To answer the original question. Yes, it will speed things up due to Kickstart being re-located in 32bit Fast RAM. But, probably no faster than other ROM mappers. Edit: Piru already answered while I was (slowly) typing).
