There was a problem hiding this comment.
I suggest making the default 2 in the interests of working well in memory-constrained environments. Users can lift this to 4 and beyond if they know they have the RAM and need for it. OTOH, it looks like the other defaults are set for performance mode, so maybe 4 is reasonable.
