Time to first byte/wait time high
I migrated a site that was previously hosted elsewhere to a 4 CPU droplet.
The wait time more than doubled here on a droplet.
The site is slower to browse, it's even obvious for a human being, even though I use a CDN, minify HTML/CSS, use other cache solutions like I did on the previous server. Google Speed Insights showed the time to connect as an issue which wasn't the case on the previous server (which was running on an older CPU with HDD).
GT Metrix waterfall show a wait time of over 800ms on average, while it was less than 300ms before.
I come from a dedicated server, so maybe that's one of the cons with a VPS but I wasn't expecting such a difference.
CPU and RAM are consistently low so that isn't the problem either.
I use Server Pilot as control panel.
Any help would be appreciated.
