If you learned something from the exercise, then it had value, but as for seeing any performance increase as a result, I doubt it. Most of the recipes you may be finding on the Web for this trick target Soekris-like systems which measure in the ~500MHz range & have limited RAM. Moving /tmp to RAM is done more to save writes to
(older) CF cards to extend their lifetime than to boost performance. Your PPC Mac mini is a 1.4GHz system which doesn't have the same constraints
(solid-state storage).
If you have concerns about performance, study both the manpage to
top(1) & it output. If the system is inordinately swapping, then moving /tmp to RAM
might be called for, but I suspect the performance increase experienced will be negligible.
As an anecdote, when Hitachi 7200rpm laptop drives first came out, I immediately went out & put
(an unauthorized) one in a IBM Thinkpad which originally had a factory-installed 5400rpm drive. The perceptible difference between drives when running OpenBSD were nearly negligible, & the 7200rpm drive ran warmer. Eventually, IBM added a whining beep
(because the drive was unauthorized...) in a BIOS update which prompted me to just get a bigger drive from them, & for heat reasons, they were only selling 5400rpm drives. I've never regretted downgrading back to a slower drive. Given the algorithms OpenBSD employs with disk writes
(& when to do them...), I didn't find such performance tricks very beneficial. At least, that has been my experience.
