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?

Plan Name Web Perf Raw CPU Power Perf Stability Disk IO Perf Network Perf

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 IONOS by 1&1 and 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
Cloud Server XL 52.6ms
VPS L 52.9ms
Cloud Server L 54.6ms
VPS M 55.4ms
Cloud Server RAM L 57.9ms
Cloud Server S 58.0ms
2GB 1 core 46.5ms
4GB 2 cores 47.4ms
8GB 4 cores 50.0ms
1GB 0.5 core 64.0ms
12GB 6 cores 64.4ms

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.

Network Transfers

We have performed large file transfers from the IONOS by 1&1 and 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
Cloud Server S 353.7Mbps
Cloud Server L 355.3Mbps
VPS L 360.0Mbps
VPS M 373.3Mbps
Cloud Server XL 383.3Mbps
Cloud Server RAM L 384.1Mbps
Cloud Server M 397.5Mbps
1GB 0.5 core 452.4Mbps
2GB 1 core 453.7Mbps
12GB 6 cores 468.4Mbps
8GB 4 cores 476.7Mbps
4GB 2 cores 481.4Mbps

Network Transfers measurements including download and upload speeds can be compared for IONOS by 1&1 and 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
Cloud Server S 3247.7
VPS M 6170.1
Cloud Server RAM L 6442.0
Cloud Server L 6502.3
VPS L 6508.9
Cloud Server M 6548.3
Cloud Server XL 12376.5
1GB 0.5 core 1512.6
2GB 1 core 3885.1
4GB 2 cores 3912.4
12GB 6 cores 8617.3
8GB 4 cores 14853.2

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
VPS L 316.2ms
Cloud Server RAM L 316.4ms
Cloud Server XL 322.2ms
Cloud Server S 497.0ms
Cloud Server M 507.0ms
12GB 6 cores 503.2ms
2GB 1 core 510.0ms
8GB 4 cores 528.4ms

Detailed remote timings measurements including connection time, TLS handshake time, and response time can be compared for IONOS by 1&1 and on the Remote Timings Comparison page.
