How to overclock macMini (i5 2.6GHz 8gb(1600MHz DDR3) Intel Iris 1536MB)?

Question

Mac Mini

How to overclock Minik? )
My Air (i5 1666GHz 4gb ram), for example, is two times less in terms of performance, but it assembles projects two or more times faster, but at the same time it heats up to 80-90 (during assembly or some other significant load
) same time, macMini(late 2014 new*) - no strain at all.
CPU runs 10 - 30% sometimes up to 50%. The temperature is 40-50 mainly, with a voltage of 60-70.
The only drawdown in comparison with Air is that it has an HDD instead of a flashSSD.
Really HDD so reduces performance?
I just don’t believe that it slows down (under load) and thinks for so long because of the operative - because it’s 8
new, what’s wrong;) ??
Do you have any thoughts or has anyone done this?

Answer 1

The HDD has a very strong influence on the assembly of the project. If we are talking about Xcode. During assembly, files are read, compiled into object files, which are written to disk. In macboock air, ssd read write speed is 730 mb/s, and mac-mini is about 100 mb/s. So calculate how much slower your project can be built. And if, at the same time, you have a bunch of other programs open that hang in memory, then swap will be used (an analogue of Windows swap, this is when the hard disk is used as RAM), which can slow down not only writing object files, but also compilation.
With the release of 9 xcode, they will introduce an incremental build (only changed files will be rebuilt), maybe then it will not hurt you to build projects. In general, I recommend buying an ssd.

Answer 2

Air: 200 to Write
400 to Read
Mac mini:
100 to Write
100 to Read
