CPU is not enough: the network is capacity planning
Teams often focus on cores and RAM when picking dedicated servers, yet user experience depends on uplink speed, packet loss and international path quality. At KuzeyDC in Istanbul, carrier-neutral design and strong peering make the same hardware perform differently.
1G or 10G?
- 1G: moderate traffic, business apps, limited backup windows
- 10G: media, heavy backups, high concurrent downloads, low-latency cluster traffic
Port speed alone is not enough—measure switch oversubscription, CRC errors and whether jumbo frames are needed.
Commit, burst and fair use
“Commit” is the guaranteed level; burst covers short spikes. If billing uses 95th percentile, watch graphs for 30 days. Read fair-use clauses in the contract.
- Measure peak Mbps and 95th percentile
- Account for backup windows separately
- Split domestic vs international traffic
The right uplink and clean routes deliver NVMe performance to users. Choose by measured traffic profile, not the cheapest port.
