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?

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 Contabo and Genesis VMs. 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
VDS S 47.6ms
Preview VDS L 48.2ms
S SSD 95.8ms
M SSD 96.0ms
vm.t5sd.4xlarge 40.8ms
vm.c5sd.2xlarge 42.2ms
vm.c5sd.xlarge 43.8ms

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 Contabo and Genesis VMs. These are the Sysbench CPU test results:

Rate of operations

Higher is better

Plan Operations per second
VPS 300 459.5
S SSD 969.6
M SSD 1509.4
VDS S 1889.5
Preview VDS L 3781.0
vm.t5sd.4xlarge 480.7
vm.c5sd.xlarge 1012.4
vm.c5sd.2xlarge 2031.8

Sysbench Disk IO Performance

We ran the full suite of Sysbench tests on VPS plans of Contabo and Genesis VMs. These are the Sysbench Disk IO Random Read test results:

Rate of operations

Higher is better

Plan MiB per second
VPS 300 110.6
S SSD 138.7
M SSD 380.0
VDS S 448.8
Preview VDS L 678.3
vm.t5sd.4xlarge 16.5
vm.c5sd.xlarge 18.9
vm.c5sd.2xlarge 29.1

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 Contabo and Genesis VMs.

Network Transfers

We have performed large file transfers from the Contabo and Genesis VMs 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
VPS 300 99.9Mbps
S SSD 195.3Mbps
VDS S 248.1Mbps
M SSD 375.8Mbps
Preview VDS L 684.7Mbps
vm.c5sd.xlarge 718.4Mbps
vm.c5sd.2xlarge 934.9Mbps
vm.t5sd.4xlarge 1246.1Mbps

Network Transfers measurements including download and upload speeds can be compared for Contabo and Genesis VMs 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
VPS 300 1798.5
VDS S 3318.1
S SSD 4070.3
Preview VDS L 4181.6
M SSD 7037.9
vm.t5sd.4xlarge 4482.7
vm.c5sd.xlarge 8849.4
vm.c5sd.2xlarge 17578.6

Review and compare endurance test results for Contabo and Genesis VMs on the Sustained CPU Endurance Comparison page.

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
M SSD 484.8ms
VPS 300 492.0ms
S SSD 518.8ms
vm.c5sd.xlarge 322.8ms
vm.t5sd.4xlarge 323.8ms

Detailed remote timings measurements including connection time, TLS handshake time, and response time can be compared for Contabo and Genesis VMs on the Remote Timings Comparison page.
