Which tariff should I choose?

Suppose your site uses a php script that executes 20 queries against the database, loads 10 static images.
The page is generated in 2 seconds, at the same time 5 users can access the page. T
ake the VDS-Start tariff plan (from the first table): The MySQL query is executed for 1/6722 = 0.000149 seconds
The query for "statics" is performed for 1/3487 = 0.000287 sec
Processing PHP script takes 1/595 = 0.00168 seconds The execution time can be calculated by adding the time costs of the MySQL and Apache services: 0.00168 + (20 × 0.000149) + (10 × 0.000287) = 0.00753 seconds

These numbers apply only to ideal conditions. It takes a while until the tcp connection to the server is established, as long as the browser generates the request and processes the response.
But, knowing the real speed of the application on VDS-Start, you can calculate the difference in performance at the rates and choose the right one.
You need to understand that the choice of tariff depends on the specifics of your application and its "needs".
For example, the Start tariff is not intended for serious projects with a heavy load - not enough RAM, only 1GB. If you need more RAM to execute the scripts of your project, it's better to take the tariff higher. It also has more disk space and cores.
The latter, when properly configured, will allow you to quickly cope with a larger number of client requests. SSD-drives are required if the application has a need for frequent and fast requests for an I / O operation.
You will notice a significant increase in the speed of access to the disk. Tariffs Forsage line allow you to flexibly configure VDS. And get the amount of resources inaccessible within the main line.
