hardware requirements

My client has performance issues. I believe this is because
a) customized code
b) there are two different DB on one server

I have not found any description of hardware requirements.
Thus, I would like to ask - whether it would be ok to have DB on virtual server with vCPU 2core, vRAM 8GB, SSD 100GB.
Would it be enough? There are about 1000 products in multiple categories, about 1200 visits per day (there is no information for concurrent users count).

It will suggest you where you should work. There are lots of parameters causes performance issues.

Here is related post. And there are many related post on the forum: https://www.nopcommerce.com/boards/t/19480/hardware-requirements-for-better-performance.aspx  

Customized code could be the issue or may be not, you can check using mini profiler.
Moreover, other things which also you can taking care of like:

- Aggressively use caching where ever you can
- Remove plugins not used
- Disabled features not required
- You need a very powerful dedicated Server (suggest to use Azure cloud hosting)
- Use CDN (We've build a plugin, will publish it soon)
- Use separate db server
