Hello,
I can confirm the problem: link
I also had the same problem about six months ago, but it was resolved with another update and everything went back to normal.
Now, with a fresh installation, I am experiencing the same issue again, where it runs slower even though the server has two additional CPU cores. The hosting provider and CPU model remain the same.
The only difference is that I am now using Ubuntu 22.04 (previously Debian 12 with MariaDB 10.11) with MariaDB 10.6 and installation with “–multiphp yes” option. However, this should not have any significant impact that would cause constant timeouts, which I did not have before.
Today or tomorrow, I will try using MyVesta. On another server with HestiaCP v1.8.7 and two additional CPU cores but higher load due to two large websites running, using Ubuntu 22.04 and MariaDB 10.11, it works much better.
