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.

How are grades calculated?

VPS Instance Provisioning Time

This is the average time it took to create an instance for Alibaba Cloud and OVH Public Cloud from instance order to instance accepting connections.

All VPS provisioning times

Alibaba Cloud OVH Public Cloud
Number of instance creations in sample 4 3

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 Alibaba Cloud and OVH Public Cloud. 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
OVHCloud S1-4 91.0ms
OVHCloud S1-8 88.0ms
OVHCloud B2-7 70.0ms
OVHCloud C2-7 62.0ms
Alibaba 1GB 1 core 84.0ms
Alibaba ecs.t5-lc1m1.small 68.0ms
Alibaba ecs-t5-c1m1-large 55.0ms
Alibaba ecs.n4.large 66.0ms
Alibaba ecs.c5.large 65.0ms

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 Alibaba Cloud and OVH Public Cloud. These are the Sysbench CPU test results:

Rate of operations

Higher is better

Provider Plan Operations per second
OVHCloud S1-4 302.9
OVHCloud B2-7 651.4
OVHCloud C2-7 777.4
Alibaba 1GB 1 core 317.5
Alibaba ecs.t5-lc1m1.small 328.4
Alibaba ecs-t5-c1m1-large 657.6
Alibaba ecs.n4.large 759.2
Alibaba ecs.c5.large 556.0

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 Alibaba Cloud and OVH Public Cloud.

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

Provider Plan Average remote request duration
OVHCloud S1-4 527.2ms
OVHCloud S1-8 388.8ms
OVHCloud B2-7 493.0ms
OVHCloud C2-7 483.6ms
Alibaba 1GB 1 core 504.4ms
Alibaba ecs.t5-lc1m1.small 335.0ms
Alibaba ecs-t5-c1m1-large 450.8ms
Alibaba ecs.n4.large 495.6ms
Alibaba ecs.c5.large 508.0ms

Detailed remote timings measurements including connection time, TLS handshake time, and response time can be compared for Alibaba Cloud and OVH Public Cloud on the Remote Timings Comparison page.

Network Transfers

We have performed large file transfers from the Alibaba Cloud and OVH Public Cloud 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
OVHCloud S1-4 98.5Mbps
OVHCloud B2-7 242.3Mbps
OVHCloud C2-7 475.8Mbps
Alibaba 1GB 1 core 317.7Mbps
Alibaba ecs.t5-lc1m1.small 80.9Mbps
Alibaba ecs-t5-c1m1-large 114.8Mbps
Alibaba ecs.n4.large 110.6Mbps
Alibaba ecs.c5.large 109.9Mbps

Network Transfers measurements including download and upload speeds can be compared for Alibaba Cloud and OVH Public Cloud 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

Provider Plan Average ops/hour
OVHCloud S1-4 1575.6
OVHCloud S1-8 3338.2
OVHCloud B2-7 2894.4
OVHCloud C2-7 3399.1
Alibaba 1GB 1 core 1435.6
Alibaba ecs.t5-lc1m1.small 957.9
Alibaba ecs-t5-c1m1-large 3185.5
