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.

Network Transfers

We have performed large file transfers from the Contabo and Kamatera 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.

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.

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).
