UltaHost Dedicated VDS vs Hostinger KVM NVMe VPS for PostgreSQL 17
Database latency p99 spikes come from two bottlenecks: shared hypervisor CPU steal (%st) during heavy queries and shared NVMe queue contention during checkpoints. Picking KVM vs VDS comes down to sustained concurrency and RAM ceiling.

PGSizer Engineering Decision Framework for VDS-VS-KVM
- Deploy on Hostinger KVM 4 ($10.49) or KVM 8 ($19.99) for 90% of early-to-mid SaaS apps under 200GB where shared_buffers <= 8GB keeps hot B-Tree indexes effortlessly in RAM.
- Upgrade to UltaHost 64GB/128GB VDS as soon as iostat/top shows >2% CPU steal, pgvector HNSW graphs exceed 20GB, or heavy analytical reporting runs concurrently with OLTP writes.
- Offload your public web frontend or marketing site onto Hostinger Cloud Web so 100% of your database node RAM stays reserved for Postgres!

PGSizer Technical Q&A for VDS-VS-KVM
How do I check if noisy-neighbor CPU steal is hurting my Postgres P99?
Run vmstat 1 or sar -u 2 10 during peak traffic and inspect the %st (steal time) column. Anything consistently above 2.5% stretches LWLock acquisition times inside Postgres and signals it is time for a Dedicated VDS.
