Designer 4.7.3 speed/memory usage

Running 4.7.3 for a while now on different machines and platforms (Windows 7 10 & macOS Mojave) and get the impression that it uses up memory a lot faster than 4.7.2 did. Also startup time has gone up a lot, it seems.

Is that just me? Anyone else seeing similar differences between 4.7.2 and 4.7.3?
