They are completely performant enough to serve small static websites, if you have low traffic (it should be confortable with a few connections per second). I think another limiting factor to look at is your upload bandwith. If it's too low, then it will saturate and your conection will be very slow. Some ISP provide asymetric bandwith (much higher download than upload), so that's not the best case. If you have fiber, then you're absolutely good to go. If your blog is featured on HN first-page, then it certainly won't handle the load with a RPI. But for most blogs, it should be enough.
