How to calculate how much traffic my VPS will withstand?

Question

Nginx

I use VPS for several sites (corporate), I send traffic to them from the context, and also come from organic.
Please tell me how to calculate how much traffic my VPS will withstand? I've heard that it's better to use regular hosting, as the sites are running on more powerful servers there..
When using Xen virtualization, 2000 MHz and 256 MB memory, hybrid disk (SSD + SATA), centos6-x86_64 ( https://hosting. reg.ru/vps/plan/XEN-2-0615)

Answer 1

ab -n 10000 -c 100 site.name

Answer 2

I would calculate the structure of visits by site using weekly logs and, keeping the proportions, I would start loading testing...

Answer 4

with this amount of memory, not at all) even 10 online users will be able to put your VPS on the dynamics, unless you have static sites of course.

Answer 5

Evaluate the loading of your web application on your own visit (no tests needed). In most cases, the bottleneck is the site code. On the Internet, you will find tons of articles on how to optimize the cheapest VPS. All this will be in vain if the generation of one page of your site requires 10% of server resources.
To debug a site locally, use xhprof or xdebug .

Answer 6

Memory 256MB is the bottleneck. I don't understand at all why to scoff at myself like that, if servers with 1 or 2 GB cost absolutely adequate money.

Answer 7

As you have already been told - there is very little memory, 1GB, and better look for 2GB, then you can put a lot of things into memory and everything will give faster at times.
