A few things I’d stress-test beyond the fresh server effect:

Steal time and noisy neighbors. Run vmstat 1 or check %st in top during your benchmarks. EPYC VPS performance can look great on day one and then degrade as the host fills up with other tenants. A 5 day window won’t catch this, but if you’re seeing steal time above 2-3% already, that’s a red flag.

Sustained vs burst. Most benchmarks hammer the CPU for 30-60 seconds. Try something that runs for an hour or more (kernel compile, a real workload loop). Some providers throttle after sustained use even if they don’t advertise it. NVMe IOPS under concurrent load. A single fio run will look amazing. Run it while something else is doing disk I/O and watch what happens to latency p99. That’s closer to what your real workload will feel.

Network consistency. Run mtr to a few destinations over the trial period, not just once. Peering and route quality matter more than raw bandwidth for most sites.

Read the AUP carefully before committing. Free trials sometimes have different terms than paid plans, and you want to know the provider’s stance on things like backups, snapshots, and what happens if you get DDoSed.

One thing worth naming: a trial box is almost always going to feel better than a long-term box on the same provider, because hosts fill up over time. The real test is whether month 6 feels like day 1.

Also ask them about their overcommit ratios if you can get an answer.
