I am currently using a VPS which is virtualised with Virtuozzo and sometimes my blog is starting to deliver in 150ms till 350ms (server response).
I assume that the virtualisation is the bottle neck because as I read Virtuozzo does have only one Kernel which results also in performance issues. May I am wrong, I am not that expert, that's why I am asking here. ;)
A new idea grow in my head: I want to have my wordpress blog fast (500 unique visitors a day, and also running Confluence, JIRA and Nextcloud on that VPS). So what about renting a Dedicated Server with NVMe. A performance benefit would also be the Dedication and an extra One the NVMe SSD. What do you think about that? Or should I just look after a Hoster which is not using Virtuaozzo? What would you recommend instead?
I hope I can profit from your experience and knowledge.
Thank you! :)
P.S.: On wordpress blogsite everything I know is done for page speed optimization. (Combining, minifying CSS/JS, optimizing pictures and so on...)
