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.
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.
