speed problem with wordpress site
Im moving my site, a wordpress blog from a shared host to DO.
At that time my site PageSpeed desktop/mobile score: 70/56
When i'm testing my copied site on DO 512Mb via DO IP -> PageSpeed 90/70
Then I pointed nameserver to DO -> PageSpeed now even slower 70/72
though my site is small just few hundred visits/day and CPU used 30%, RAM <50%, Data 1Gb.
I tried another solution by upgrading my server to 1Gb RAM, now speed has no improvement but even worse 64/68
So what is the problem with my site speed?
