Upgrade the memory of your 2018 Mac mini up to 64GB

Optimizing Photoshop CS5 — 5X slower or 3X faster than CS4!

Amazing but true: how you configure and use Photoshop CS5 can make an enormous difference in performance. It can be 5X slower than CS4, or 3X faster. Wow!

But there is also a “warm up” issue with memory allocation that can mean a 6X variation in performance with CS5 that can make it 2-4X slower than CS4 (depending on the size of the job).

The good news is that once “warmed up”, the 64-bit CS5 is 3.3X faster on the diglloydHuge benchmark (with 64GB memory installed on 8-core Mac Pro).

See my revealing Optimizing Photoshop CS5 report.
