Still kicking around this idea and didn’t see it addressed in any of the threads before the forum closed.

If one made an all ssd pool, would a log/cache drive just slow you down? Would zil slow you down?

I would guess not, you would still be spreading your IOPs. I haven't tried an all SSD pool, but I have tried adding a lump of spinning rust as a log to pool of identical dives and it did give a small improvement to NFS performance.
