Is "Can 512MB VPS handle 8k visitors per day? Yep!" still valid?

[ar2020]

Hi,

My website had handled 5k visitors for years with 768MB RAM without changing any default settings. When I needed to change my server from Virtuozzo to Kronos Cloud with 1GB RAM, I installed Centos, Vesta and My Joomla website. Mariadb started to stop randomly in a few hours a few times a day. Logs indicated that more RAM is necessary. Besides this, fail2ban does not work.
Having tried some unsuccesful trials such as changing default settings of database I concluded that something has changed in Vesta that made impossible to have past experience.

Before farewell to Vesta I decided to write here. Is there anyone who could overcame similar situation recently?

Of cource, 512 MB can handle 8K visitors per day, and 10k and maybe 20K

RAM not is ALL, this will depend of your content, if one of your web script use need 1 GB of ram to work of course you need some bigger

This will depend of your website requirement, php / sql query optimization

If you use some CMS like wordpress, with a lot of plugins and big database you cant run it in 512MB

So this depends of your site optimization, if you run some HTML site with a lite php scripts and not much sql querys this will work fine in 512 MB but if is PHP / MYSQL intensive you need look closer and optimice all with much caches
