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 or stability (cpu, disk IO, network IO...) and is made of one or more metrics measured during the tests.

Grades are evenly distributed between A and F. A is best, F is worst.

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

VPS Instance Provisioning Time

This is the average time it took to create an instance for Microsoft Azure and IO Zoom from instance order to instance accepting connections.

All VPS provisioning times

Microsoft Azure IO Zoom
Number of instance creations in sample 9 1
Provisioning time in seconds 125s 600s

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 cloud servers from Microsoft Azure and IO Zoom. This is the average response time measured locally on the VPS for each plan we tested.



Local Response Time per Plan

Lower is better

Plan Average response time
Azure
F2s v2 48.0ms
B2MS 53.0ms
B1MS 56.0ms
B2s 58.0ms
F1 61.0ms
F1s 71.0ms
IOZoom
Cloud 1GB 101.0ms

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 Performance

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



Rate of operations

Higher is better

Plan Operations per second
Azure
F1 317.7
F1s 322.6
B1MS 367.9
D2 v3 488.9
D2a v4 647.6
B2s 687.5
F2s v2 701.9
B2MS 714.3
IOZoom
Cloud 1GB 256.3

Sysbench Disk IO Performance

We ran the full suite of Sysbench tests on VPS plans of Microsoft Azure and IO Zoom. These are the Sysbench Disk IO Random Read test results:



Rate of operations

Higher is better

Plan MiB per second
Azure
F1 1.8
B1MS 4.3
B2s 6.3
F1s 15.9
F2s v2 22.1
D2a v4 23.0
B2MS 23.2
D2 v3 40.8

Cloud 1GB 29.7

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 IO Zoom.


Network Transfers

We have performed large file transfers from the Microsoft Azure and IO Zoom 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

Plan Network Download Speed
Azure
F2s v2 284.9Mbps
B2MS 759.1Mbps
F1s 766.6Mbps
B2s 1250.5Mbps
D2 v3 1323.2Mbps
B1MS 1410.0Mbps
F1 1416.9Mbps
D2a v4 2663.4Mbps
IOZoom
Cloud 1GB 95.9Mbps

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


Sustained CPU Endurance Tests

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

This test 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 may be.


Average number of operations per hour

Higher is better

Plan Average ops/hour
Azure
B1MS 1131.4
F1 1596.9
B2s 2349.5
F1s 2966.8
B2MS 3012.4

Remote Timings

During the entire duration of the web performance test, we collected web response times from 5 different locations in the world. The chart below reports the connection establishment time + TLS handshake latency from all 5 locations. (That excludes the time spent on the server that is already measured in web response times above and it also excludes the DNS resolution time since it is not dependent on the provider).


Remote Latency per Plan

Lower is better

Plan Average remote request duration
Azure
F2s v2 295.6ms
B2s 317.2ms
B1MS 318.6ms
F1s 319.8ms
B2MS 321.8ms
F1 322.8ms
IOZoom
Cloud 1GB 341.6ms

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