tsgo is real and the performance jump is verifiable — but the beta has documented limits that most posts quietly ignore. Here's the concrete criteria for deciding whether to explore it today or wait for stable.

Same backend, same database, same k6. In the first runs it looked like Embedded GlassFish was on top. When I fixed JDK, warmup, window, heap, and DB attribution, the story changed: Spring Boot ended up with the best local profile for this workload. Payara Micro was the cleanest Jakarta EE by check failures. GlassFish surprised by being viable.

Prisma in Next.js 16 Server Actions has an N+1 vector that doesn't exist in classic API routes. The culprit isn't the ORM — it's how Actions compose. Here are the patterns that prevent it.

I built a reproducible lab with Spring Boot 3.5, Java 21, AppCDS, AOT, and GraalVM Native. The conclusion isn't that native wins or that classic JVM loses: it's that in 2026, comparing only startup time is the fastest way to make an architecture decision with incomplete data.

I built a reproducible lab to compare Prisma 5 against Spring Boot JdbcTemplate on the same PostgreSQL 16. What I found wasn't a winner: it was that query shape and N+1 explain almost everything, and blaming the ORM is too easy.

A low p95 with a 97% error rate isn't a fast pool — it's a pool that fails fast. I built a reproducible experiment with Spring Boot 3, PostgreSQL, and k6 to understand which signals actually matter — and which ones deceive you.

Spring Boot works very well in production, but its defaults do not always fit PaaS constraints, tight memory, and real observability. These are the points worth reviewing before trusting the initial setup.

434 points on HN argue that Async Rust is still a glorified MVP. I replicated every concrete criticism against reproducible example code: executor leaks, cancellation safety, Pin hell. My conclusion is more uncomfortable than the original post.

489 + 506 points on HN. Bun ports to Rust and everyone has a take. I ran the benchmarks on my real stack before opening my mouth. The uncomfortable result: the underlying language matters less than the hype suggests.

Architecture, real systems, product decisions and technical lessons. Everything reviewed with my own judgment before it ships.
