The SD card write speed makes the most difference in my projects. The speed printed on the card, C10 etc, is mostly a fraudulent misrepresentation of a very short initial burst of speed. Spending an extra $10 on a card can give you 10x write speed.

Placing temporary files into ram looks like the next most useful step if your ram is not flooded by something else. There are a few posts on using ram. I have used it on a Pi 3 because the ram is rarely more than half used. I stopped using it because the smaller Pi Zero memory is easily flooded.

There are numerous threads on SD card speed/benchmarks so hope I don't derail this thread by mentioning it: personally feel small file random read/write speed is the gold standard (as per iozone) and Samsung Evo+ the card to beat. And then overclocking the card - add dtparam=sd_overclock=100 to config.txt.

gpu_mem=256 seems overkill to me but no doubt depends what you are doing with the GPU - I get away with 64 and have no problems with general purpose video/DVD/DVB with omxplayer (which frees RAM for other purposes). Similarly prefer openbox as a desktop as it is also RAM-lite.

Add noarp to /etc/dhcpcd.conf to speed wifi connect times: saves me about 4s in systemd-analyze blame (and any reconnects) but obviously depends if (no)ARP is crucial to your network or not.
