I´m looking after a NopCommerce site.
It was running very quick and responsive when I set it up.
Now after about 2 years it loads very slowly, has nothing to do with keep alive, not only the first request is slow.
You can click around if you want to see it yourself: https://aquarius.li.
The hosting environment didn´t change, still the same server and database.
It´s running on a dedicated server at AWS and uses Cloudflare as CDN. IIS is on version 8.5 and NopCommerce on version 3.80.
The site speed is good on my development machine.
I would appreciate any suggestions about how to solve this.
