I/O rate testing is conducted with local and block storages attached to the instance. Cloud Mercato uses the well-known open-source tool FIO. To express IOPS the following parametersare used: 4K block, random access, no filesystem (except for write access with root volume and avoidance of cache and buffer.
Low-traffic WordPress blogs: A performance test showed that this instance could reliably handle 10 concurrent users with a 30-45 second think time between requests.[link]
JMeter load generators: Used for conducting performance tests on web applications.[link]
Running tests and executing operational scripts: Suitable for intermittent, low-resource tasks.[link]
Development environments: Cost-effective for small-scale development work.[link]
Performance Insights
Coming Soon...
In a WordPress blog test, memory consumption reached 57-60%, while CPU usage did not exceed 6%[link]
At 6% constant CPU usage, it would take about 50 hours to exhaust the initial 30 CPU credits[link]
T4g instances offer up to 40% better performance at 20% lower cost compared to T3 instances[link]
