Thread: Is there any performance benefit to using single regional maps on older devices?

One point: file size depends upon what's included (e.g. CSPEECH files). I don't have a reliable answer to the performance question, but if you have a large- and a small-area map including the area of interest, and enough space, you could load them both, and use them alternately to compare them. I'd like to see an answer from someone who knows, but I tend to prefer maps of the region I'm in.
