I'm getting a new Dedicated Server for Magento.
The size traffic is medium (About 1k) Daily.
Working on Fastest Theme bought from themeforest.
I need the specs as I got vps but it was slow and had so many problems after the installing.
Thanks in advance
Here's a page where you can find sample recommended Magento server specs. There's also a size-out form on the page where you can enter your URL to get a more custom recommendation (for free). A good recommendation should keep in mind a few additional factors, like peak traffic (and not only average traffic).
With correct settings and optimisations server-side you should be able to get this to work on most VPS however that is purely an assumption based on the limited information you have provided.
They key factor in getting the right size server is how many visitors vs checkouts do you have and what is the frequency of said checkouts.
Additional factors include things like how many custom modules do you have installed and how cleanly coded is your themeforest theme.
There is no special formula but plenty of people on here can provide their opinion including myself based on real world examples.
Feel free to share more info either publicly or in DM and I'd be happy to help you progress if you haven't already.
Magento 2.3.0 is having problem on the store whenever huge catalog is present. If your store is managing huge catalog, Please check the fix of catalog issue. https://github.com/magento-engcom/msi/pull/1950/files
With 1k daily visitor, a vps with 4gb ram, 4core cpu can handle your site pretty well. So if you are using dedicated, try a small dedicated option with 8gb ram, 4 core cpu (should run on SSD)
First of all, if you are tech-savvy then server management won't be a problem for you. If you aren't techie guy then, a managed hosting provider is the way to go.
Magento has explained all the server requirements that are best to offer the website speed performance. Here's the link that you can go through - official doc by Magento: https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html
I hope, this would give you a clear idea about the server requirements and specs.
If you've any other queries, feel free to let me know.
