In ArcGIS Server 10.3, does setting minimum instance to 0 cause a performance hit when the instance is requested and it has to spool up? I'm trying to squeeze some more performance out of limited hardware resources, wondering if setting less popular services to "0" won't be noticed by users.....

I haven't tested in 10.3 enough yet for comparison, but for 10.2.2 I would say "yes", users may notice a lag if it spools it up the first time, but after that, not an issue.  I have most of mine set at 0.   I don't think the lag is that noticeable, and for seldom used layers, better to not have them take resources when idle.  Base maps get used often enough that for us, that never seems to be an issue (except after a restart).

In the testing I've done so far with 10.3, I don't see many differences from 10.2.2.
