Weak processor for the image server?

Question

Network administration

Do you need a server that will host only images, the site itself will be on a different server, does RAM and processor matter? Atom N2800, 4 GB RAM is suitable for these purposes?

Answer 1

For static, more than suitable. Loading there is minimal, unless, of course, on a collective farm.
If everything is in memory, then you can even use the HDD, everything will fly.
Use Nginx and open_file_cache for fastcgi_cache dynamics, but I understand that this is already superfluous.
Well, do not forget to check what load the server can withstand:
apt install -y apache2utils
ab -n 100 -c 10 https://mysite.ru/pict.jpg
-n - number of requests
-с - number of parallel requests

Answer 2

It doesn’t, the pictures will be distributed ok, usually such servers just have a channel of one hundred megabits
