Running the numbers on combo deals versus decoupled procurement. Typical virtualization tax on bundled platforms: 15-30% overhead from control panel integrations. Kernel-level isolation suffers when domain DNS management shares cgroup limits with web server processes.
Question: has anyone benchmarked TTFB on bundled versus separate? My hypothesis: separate wins on I/O scheduling alone. OpenVZ bundles especially suspect here. — https://bench.sh
