    Hi,
    Firstly, I'm so sorry if my English is difficult to understand as I'm not a native speaker and newbie in this field.
    I'm building 2 websites that they get some information from other websites by a request. One website (Site 1) is hosting on a shared-hosting (2GB RAM, 1.2 CPU Cores) and another (Site 2) is hosting on a vps (2GB RAM, 1 Core).
    The problem is Site 1 need only 10-15 seconds to finish the request above, but Site 2 need 40-60 seconds.
    I try to figure out, and I think MySQL database is slow.
    I try some test that I learn from this forum and here is the result:

    Code:
    # dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync && rm -rf test
    16384+0 records in
    16384+0 records out
    1073741824 bytes (1.1 GB) copied, 144.894 s, 7.4 MB/s

    Who's your web hosts? Could just be poor performing VPS /web host providers too. You can use hourly billed VPS providers like Upcloud, DigitalOcean, Vultr, Linode to spin up a test VPS with Centmin Mod and a copy of your site and test and compare performance and speed too.

    Take a read of WebPerf - PageSpeed - Google Page Speed Insights and Google Core Web Vital metrics and use the page speed testing tools mentioned to test your sites and see what they reveal. Geographical distance matters too, so use testing tools in various country's servers to see if there's a difference.
