Your VPS is allocated a specific number of vCPUs, but how these are enforced varies by provider. Some providers allow CPU bursting — using more than your allocation temporarily when the host server has spare capacity. Others strictly enforce limits. Understanding this distinction affects how your applications perform under load. Monitor CPU usage with top, htop, or mpstat. If you consistently hit your CPU limit, it’s time to upgrade rather than hoping burst capacity will be available.
CPU Limits and Fair Use
Your VPS is allocated a specific number of vCPUs, but how these are enforced varies by provider. Some providers allow CPU bursting — using more than your allocation temporarily when the host server has spare capacity. Others strictly enforce limits. Understanding this distinction affects how your applications perform under load. Monitor CPU usage with top, htop, or mpstat. If you consistently hit your CPU limit, it’s time to upgrade rather than hoping burst capacity will be available.
RAM Management
RAM is typically a hard limit — if your VPS has 4GB, that’s all you get. When you hit the limit, the Linux OOM (Out of Memory) killer terminates processes, often crashing your web server or database. Monitor RAM usage with free -h and set up alerts at 80% utilization. Configure swap space as a safety net (not a primary resource): fallocate -l 2G /swapfile && mkswap /swapfile && swapon /swapfile. Optimize application memory usage — PHP-FPM workers, database buffer pools, and cache sizes are your main tuning points.
Disk and Bandwidth
Monitor disk usage regularly with df -h and set alerts at 85%. Log files, database growth, and user uploads are the usual suspects. Configure logrotate and set database table maintenance schedules. Bandwidth limits typically reset monthly — monitor with vnstat. Most web hosting workloads never hit bandwidth limits, but video hosting or file sharing can. Velox Media’s dedicated account management include generous resource allocations designed for real-world hosting workloads.
