Recommended CPU/RAM VPS settings to query 50,000 entries I'm running a very simple query on a text field...

{% set query = craft.request.getQuery('email') %}


Locally, with one entry on my machine, I'm getting a response time of 332ms. We were assuming around 3,000 total entries, but 3 days in, I'm at 15,000 and climbing by hundreds per hour. 

What would be a good starting point for CPU/RAM on a VPS if I assume that we could hit 50,000?
The CPU won't be the issue more the RAM if you expect to pull in all those results. But it's not much anyways.... A 1 CPU/1GB RAM on Digitalocean will be enough.
