I find myself unsure about how much my character should do in a single roleplay post (1x1 format). Should I do a small amount of stuff with greater detail or a larger amount of stuff with less detail? A balance?

Sometimes I find that if I do very little, it might not be enough to move the RP forward (and may also be a relatively shorter and/or less interesting post to respond to). But if I do a lot, it forces my partner to have to address and react to all the things I did, which can kind of mess with interactive flow, as well as turn into unintentionally controlling their character in that it may deny their ability to respond appropriately to one or more of my actions.

So how do I know how much my character should do and where a good "end point" to my post should be?
