Microsoft Azure Review

All grades are based on tests run by VpsBenchmarks on each VPS plan. There are 4 types of tests: web, sysbench, endurance and remote timings. Each grade is the combination of one or more test metric.

Given a metric for a plan and a test, the grade is determined relative to the same metric from all other plans. A plan with a metric in the top 33% above the average will get an A, a plan with a metric in the bottom 33% below the average will get an F. Relevant single metric grades are then weighted and combined to give the grades reported on the website.

Note: The VPS plan price is not a factor in calculating the grades. More expensive plans with higher specs are likely to get higher grades than cheaper ones.

Web Performance

The Web Performance is made of the Web test average response time and 99th percentile response time.

Raw CPU Power

The Raw CPU Capacity grade is made of the Sysbench CPU test number of operations per second and of the Endurance test number of iterations per hour metric.

Performance Stability

The Performance Stability grade is made of the Web test average response time standard deviation and the Endurance test number of iterations per hour standard deviation.

Disk IO Performance

The Disk IO Performance grade is made of the Sysbench test sequential disk write speed, randow read/write speed and of the Web test database average response time.

Network Performance

The Network Performance grade is made of Remote Timimgs times for establising the TCP connection and for the TLS handshake from West US, East US, West Europe and Japan.
