Performance Grades

To summarize the performance of each VPS plan, we generated grades based on the various tests that were run: web, sysbench, endurance and remote timing tests. Each grade focuses on one aspect of the VPS speed (cpu, disk IO, network IO...) and can be made of one or more of the metrics generated during the tests.

Grade A is best, grade F is worst.

Follow the letter links to find the test results backing the grade.

How are grades calculated?

Plan Name Web Performance Raw CPU Power Performance Stability Disk IO Performance Network Performance
t2-micro B F E E C
t3.small C C D D D
B1MS B F D E C
t2-small B F D C C
t3-medium B D D D B
B2s B D F D B
A1 v2 F F D F D
t2-medium B D D D D
F1 C E E E B
F1s B E D D B
m5a.large C D D D D
m5.large B C C C B


In Depth...

The grades above are based on the following test results.


Web Response Times

We ran a database intensive web application with ~100,000 hits per day for several days on VPSs from Microsoft Azure and Amazon EC2. This is the average response time measured locally on the VPS for each plan we tested.


Local Response Time per Plan

Lower is better

Provider Plan Average response time
EC2 t2-micro 63.0ms
EC2 t3.small 62.0ms
EC2 t2-small 53.0ms
EC2 t3-medium 55.0ms
EC2 t2-medium 52.0ms
EC2 m5a.large 66.0ms
EC2 m5.large 50.0ms
Azure B1MS 62.0ms
Azure B2s 57.0ms
Azure A1 v2 196.0ms
Azure F1 61.0ms
Azure F1s 61.0ms


During the Web Test, we collect response time metrics, CPU metrics and database performance metrics. All of those are measured locally on the VPS running the web server. All metrics can be compared on the Web Performance Comparison page.


Sysbench CPU Performances

We ran the full suite of Sysbench tests on VPS plans of Microsoft Azure and Amazon EC2. These are the Sysbench CPU test results:


Rate of operations

Higher is better

Provider Plan Operations per second
EC2 t3.small 604.7
EC2 a1.medium 897.3
EC2 t3-medium 554.2
EC2 t2-medium 701.1
EC2 m5a.large 540.7
EC2 m5.large 644.8
Azure B1MS 333.2
Azure B2s 647.0
Azure A1 v2 134.1
Azure F1 317.7


Sysbench test results are also available for random disk IO tests, sequential disk IO tests and memory tests.

Review and compare all Sysbench numbers on the Sysbench Comparison page for Microsoft Azure and Amazon EC2.


Remote Timings

During the whole duration of the web performance test, we collected web response times from 5 different locations in the world. The chart below reports the average connection + TLS handshake latency from all 5 locations.

Note: Remote timings may not be available for all plans.

Remote Latency per Plan

Lower is better

Provider Plan Average remote request duration
EC2 t2-micro 343.6ms
EC2 t3.small 359.8ms
EC2 t2-small 338.6ms
EC2 t3-medium 339.8ms
EC2 t2-medium 344.8ms
EC2 m5a.large 301.6ms
EC2 m5.large 338.8ms
Azure B1MS 318.6ms
Azure B2s 316.2ms
Azure A1 v2 324.2ms
Azure F1 270.6ms
Azure F1s 318.0ms

Detailed remote timings measurements including connection time, TLS handshake time, and response time can be compared for Microsoft Azure and Amazon EC2 on the Remote Timings Comparison page.


Network Transfers

We have performed large file transfers from the Microsoft Azure and Amazon EC2 VPS and we measured the speed of downloads and uploads.

The transfers involve multiple files, 10 threads and last for at least 10 seconds at maximum speed. The transfers are repeated 3 times from different servers and only the fastest transfer is reported here.

Download Speed per Plan

Higher is better

Provider Plan Network Download Speed
EC2 t3.small 418.7Mbps
EC2 a1.medium 181.8Mbps
EC2 t3-medium 1850.2Mbps
EC2 t2-medium 506.8Mbps
EC2 m5a.large 573.8Mbps
EC2 m5.large 629.0Mbps
Azure B1MS 904.7Mbps
Azure B2s 1415.2Mbps
Azure A1 v2 594.3Mbps
Azure F1 1416.9Mbps
Azure F1s 1599.2Mbps

Network Transfers measurements including download and upload speeds can be compared for Microsoft Azure and Amazon EC2 on the Network Transfers Comparison page.


Sustained CPU Endurance Tests

We pushed the CPU of those VPS plans very hard for 24 hours straight.

This kind of tests shows how fast the VPS can go for long periods of time, how stable the performance is and it also gives clues on how overallocated the VPSs are.

Note: Endurance metrics may not be available for all plans.

Average number of operations per hour

Higher is better

Provider Plan Average ops/hour
EC2 t2-micro 458.1
EC2 t3.small 4280.3
EC2 t2-small 1017.4
EC2 t3-medium 1732.2
EC2 t2-medium 2184.5
EC2 m5a.large 1901.8
EC2 m5.large 4587.6
Azure B1MS 1028.9
Azure B2s 2124.8
Azure A1 v2 614.5
Azure F1 1596.9
Azure F1s 1308.6
