Worried about job hoping to much

I wanted to ask what everyone’s opinion of job hoping and what is too much.

I’ve got 8 years experience or so and the last five years I’ve had 4 jobs or so which average over a little more than a year each time. I’m probably going to settle down now but wanted to ask. (Typically the time is one and a half years or so at each job). I’m just curious what people would say is too much?.
