LLM inference on CPU: sizing a server by memory bandwidth

Generating a token means reading the model's active weights once, so a CPU server's speed ceiling is its memory bandwidth divided by the model's size. The arithmetic, the catch in prompt processing, why two sockets are not twice as fast, and the workloads a big-memory EPYC box genuinely suits.

Build your own CDN: edge caches, one origin, honest numbers

A handful of caching edges in front of one origin covers most of what a commercial CDN does for a European audience, at a fraction of the per-terabyte price. The architecture, the nginx configuration that does most of the work, how users reach the nearest edge, and where the do-it-yourself version loses.

How to choose a VPS: nine numbers to check before you pay

Most VPS plan pages lead with a price and a vCPU count and leave out the numbers that decide how the machine behaves. The nine to find before you pay, what a good answer looks like, the red flags, and a worked example of matching a workload to a plan.

EPYC vs Xeon: choosing the CPU in a dedicated server

What you can rent is not this year's Xeon against this year's EPYC but an eight-year spread of generations at prices seven times apart. Per-core speed, memory bandwidth, PCIe lanes and price per core — and which of those differences your workload can actually feel.

Saturating a 100 Gbps port: what has to be true first

The port is the easy part — it is lit in an afternoon. Then the machine behind it has to produce 12.5 gigabytes every second, and each layer between the disk and the wire gets a chance to be the reason it does not. The arithmetic, in the order it fails.
