Results Summary
The scale in the charts between 0 and 100 represents the performance of this server for each metric relative to the performance of all other servers tested recently at VPSBenchmarks for that same metric.
- 100 means the server is the fastest for this metric.
- 50 means the server has exactly median performance for this metric.
- 0 means the server is the slowest for this metric.
Geekbench 6
Geekbench measures your processor's single-core and multi-core power.
| Full Test | https://browser.geekbench.com/v6/cpu/19080263 |
|---|---|
| Multi Core | 2903 |
| Single Core | 801 |
Fio
This Fio test evaluates disk performance in 4 random read and write runs with different block sizes, 50% reads and 50% writes.
All fio tests below run in asynchronous direct mode using libaio and use 2 execution threads regardless of the size of the server.
