Nginx powers over 30% of all websites, and its performance on a VPS depends heavily on proper configuration. A default install is safe but leaves significant performance on the table….

Running MySQL or MariaDB on a 1-2 GB VPS requires careful configuration. Out of the box, these databases allocate memory assuming a dedicated server with several gigabytes of RAM. On…

Linux ships with hundreds of tunables — CPU governors, scheduler settings, virtual-memory ratios, block-device queue depths — and most VPS owners either leave them at defaults or paste random sysctl…

Transparent Huge Pages (THP) were designed to make Linux’s large-page optimizations automatic: the kernel’s khugepaged thread scans memory and promotes eligible 4 KB pages into 2 MB (or 1 GB)…

SSH sessions drop when your connection drops. A long-running database migration, a package update, or a file transfer that gets interrupted means starting over. Tmux keeps your session alive on…

Database replication is often associated with multi-server architectures, but you can run a fully functional MySQL master-slave setup on a single VPS. Why would you do that? For backups without…

SSH brute-force attacks are one of the most common threats facing any internet-connected VPS. Automated bots scan the entire IPv4 address space every few minutes, trying default credentials and common…

Network latency and throughput are critical for web applications, APIs, and real-time services. While many users focus on application-level optimizations, the Linux kernel’s network stack offers a rich set of…

Every VPS running a web application eventually needs a reverse proxy. Whether you are hosting multiple sites, running a Node.js API behind a domain, or adding TLS termination to an…
