TechnologyHow Can I Identify VPS Noisy Neighbors via CPU Steal Time?Diagnose VPS performance lag by identifying CPU steal time metrics. Use top and vmstat to detect noisy neighbors and resource contention on the hypervisor.
TechnologyDoes KVM virtualization provide more consistent disk I/O performance compared to OpenVZ or LXC containers?KVM provides superior disk I/O consistency by using dedicated block device emulation and independent guest-side scheduling, unlike the shared kernel queues in LXC or OpenVZ.
TechnologyWhen Does SQLite Row-Level Locking Impact n8n Throughput?SQLite is the default for n8n, but high execution volumes cause locking issues. Learn when to migrate to PostgreSQL and how to tune your database for reliability.
TechnologyHow long should lowering the DNS TTL before a move actually take?Lowering your DNS TTL must occur at least as many seconds before a migration as the current TTL value to ensure all caches expire before the switch.
TechnologyDoes a 4 GB VPS running several sites at once change what I should buy?Running multiple sites on a 4 GB VPS requires careful PHP-FPM and MySQL tuning to avoid OOM killer intervention. Learn how to calculate the real memory ceiling for your stack.
TechnologyHow do I check KVM against OpenVZ and LXC on a server I already pay for?Identify your server's virtualization technology using command-line tools like systemd-detect-virt and manual inspection of the proc filesystem to verify resource limits.
TechnologyHow Do I Verify If My Server Is a VDS or a VPS?To check if a server is a VDS or a VPS, you must measure CPU steal time and verify core pinning using tools like lscpu and top to detect resource oversubscription.
TechnologyDoes CPU Steal Time Change What I Should Buy?CPU steal time indicates that your virtual machine is waiting for physical CPU cycles, signaling resource contention that may necessitate a move to dedicated cores.
TechnologyWhat is a Hostname? A Complete Guide to Networking and VPS ServersA hostname is the label that identifies a machine on a network. Here is how hostnames, domains and FQDNs relate, and how to set one correctly on a VPS.
