HTTP/3 runs over QUIC, a UDP-based transport with TLS 1.3 built in. The payoff for your visitors is concrete: connection setup takes one round trip instead of two, repeat visits…
Read MoreWhich Linux Kernel Tunables Actually Move a Benchmark on a VPS (34 Tested, 8 Kept)

Most Nginx-vs-Apache comparisons stop at “Nginx is faster” and leave you to guess. The useful question is narrower: at what concurrency, on how much RAM, does each server’s process model…
Read MoreCaddy as a Production Reverse Proxy: TLS, Health Checks, Logging and Measured Overhead
Caddy is attractive precisely because it removes the two most error-prone parts of running a reverse proxy: writing TLS configuration and remembering to renew certificates. But the ten-minute setup is…
Read MoreVirtual Disk Performance Tuning: Filesystem, Scheduler and Mount Options Verified with fio
Storage is the component most often misdiagnosed on a virtual server, because the visible device is a virtual block device whose latency, queue depth and throttling behaviour are all decided…
Read MoreNginx vs Apache vs Caddy: Measured Memory, Concurrency and Tail Latency on a 4-vCPU VPS
Choosing between Nginx, Apache and Caddy is not a matter of taste once the numbers are on the table: they differ in per-connection memory, how they handle slow clients, what…
