[cybervps]

I have some really tiny vps-es, i was wondering which web servers has smallest memory requirments?

If it's a really tiny VPS, I'd focus on keeping the number of PHP-FPM workers low as well. In my experience, that's usually where most of the memory goes. The web server itself isn't the biggest problem.
