I create this tests to check how many hosts I need for my project if I build it on platipus-js platform.

First of all you should clone this repository. Next step is download and install PostgreSQL 9.6. On this page select PostgreSQL version 9.6 and your operation system. Also you need to download jmeter 3.1. Last step is create database for tests. Go to folder in wich you clone this repo. Now execute file src\app\payments-db.sql. You can do it with pgAdmin tool for example.

So for tests I used following components

1. My laptop:
   • CPU: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2592 МГц, cores 4, logical 8 x64
   • Memory: 16 Gb DDR4
   • HDD: Модель NVMe SAMSUNG MZVPV512 500Gb SSD
2. platypus-js 5.11.2
3. PostgreSQL 9.6 with config:

    max_connections = 260
    shared_buffers = 512MB
    effective_cache_size = 6GB
    work_mem = 26214kB
    maintenance_work_mem = 512MB
    min_wal_size = 2GB
    max_wal_size = 4GB
    checkpoint_completion_target = 0.9
    wal_buffers = 16MB
    default_statistics_target = 100

4. Apache Tomcat 8.5.8

In table information present in requests per second.

One note that JMeter, Apache Tomcat and PostgreSQL was ran on 1 phisical machine
