Hi folks, it's Takuya here, the solo developer of Inkdrop.
If youâve been setting up VMware Memory Tiering or thinking about it, youâve probably asked yourself at some point: what happens to Memory Large Pages? Itâs a great question, and Iâm glad youâve asked it, because the answer changes how you need to plan your capacity and configure your VMs. Let me walk you through ⌠Continued

We built the same HTTP server in Go, Bun, and Rust using two storage strategies: read the file on every request, or load everything into memory. Then we ran real benchmarks. The results are more interesting than you'd expect.
We benchmarked Cloudflare Mesh, NetBird, and Tailscale across AWS, GCP, Hetzner, and residential networks in Europe. Here's what peer-to-peer vs edge routing actually looks like in practice.

Cloudflareâs Gen 13 servers double our compute throughput by rethinking the balance between cache and cores. Moving to high-core-count AMD EPYC ⢠Turin CPUs, we traded large L3 cache for raw compute density. By running our new Rust-based FL2 stack, we completely mitigated the latency penalty to unlock twice the performance.

The power of Zig's comptime code execution
For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD.
But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size.
The Thunderbolt drive I had was capable of well over 5 GB/sec, and my 10 Gbps network connection is capable of 1 GB/sec. I even upgraded my Thunderbolt drive to Thunderbolt 5 lately... though that was not the bottleneck.

Letâs Encrypt protects a vast portion of the Web by providing TLS certificates to over 550 million websitesâa figure that has grown by 42% in the last year alone. We currently issue over 340,000 certificates per hour. To manage this immense traffic and maintain responsiveness under high demand, our infrastructure relies on rate limiting. In 2015, we introduced our first rate limiting system, built on MariaDB. It evolved alongside our rapidly growing service but eventually revealed its limits: straining database servers, forcing long reset times on subscribers, and slowing down every request.
