I just deployed my react app which shows videos on it (previews on thumbnails, etc). On my localhost, if I run the react app and the server, its very fast. Videos load fast, its responsive etc (servers are hosted elsewhere). As soon as I go on my app hosted on droplet, the website loads fast, but the server response for images, video loading is super slow. It buffers every second, loading takes long time compared with localhost.

The app is running a very light express server with pm2 and yet the cpu is always 80-100% without anyone actually accessing the website.

Why is that?

Just to add some additional info. I restarted pm2 and it dropped to 3%, but the pm2 shows 0 cpu usage and 90mb of memory usage. Leaving it overnight the droplet shows 100% spike within couple of minutes from 3% to 100% and staying 100% for the past 6 hours
