Why is my new scaled droplet (8GB RAM - 4 vCPUs) is 4 times slower than the old one?
Last Friday, August 11th 2018, I scaled my VPS for my website. As I started to receive more and more requests for LRC Maker and Downloads (Lyrics files), my CPU crossed 100% multiple times, and was averaging 80%.
The Apache server in the old VPS 4GB RAM and 2vCPUs used to load the Main Page in 200-250ms, now the new one with 8GB RAM and 4cCPUs is loading it in 900-1200ms. Just some minutes before the scale, the speed was still excellent. Now all the pages are taking 4x more times than before, I even started to loose some pageviews that kept until then increasing fastly.
I just try to update /etc/resolv.conf, without rebooting, but with no success. What could be behind such a slow performance?
