Daniel Marbach @daniel.openplace.net · 20/07/2026How do you keep performance gains without fooling yourself? The final post in my performance and benchmarking series covers useful regression gates, benchmark variance, noisy CI runners, and why human judgment still matters. www.planetgeek.ch/2026/07/20/k... #dotnet #performance 012
Daniel Marbach @daniel.openplace.net · 02/07/2026I wrote about what happens when a message handler outlives the queue lease. Renewing sounds easy until you need a renewer, mutating receipts, coordinated delete, and shutdown juggling. The first loop is easy. The edges are where the work lives. www.planetgeek.ch/2026/06/29/w... 011
Daniel Marbach @daniel.openplace.net · 22/06/2026A benchmark win is not the finish line. The real workload may tell a different story. Profile the larger execution path again to see whether the improvement compounds. www.planetgeek.ch/2026/06/22/a... 010
Daniel Marbach @daniel.openplace.net · 20/06/2026The first version of a message pump is easy. The tenth version contains: retries idempotency transactions topology monitoring The hard part isn’t the loop. It’s owning every failure mode behind the loop. www.planetgeek.ch/2026/06/20/m... #dotnet #messaging 010
Daniel Marbach @daniel.openplace.net · 15/06/2026The biggest red bar isn’t always the biggest problem. Profilers reveal costs. We set priorities. www.planetgeek.ch/2026/06/08/r... #dotnet #performance 011
Daniel Marbach @daniel.openplace.net · 13/06/2026We inherited a legacy medical invoicing system. The business wanted to expand into web shops. Same invoices. Very different failure modes. Here’s what a message queue taught us about temporal decoupling 🧵👇 www.planetgeek.ch/2026/06/13/l... 142
Daniel Marbach @daniel.openplace.net · 10/06/2026Production code is too noisy. Benchmarks are too focused. Between them sits the profiling harness. Small enough to isolate a code path. Realistic enough to expose allocations and CPU costs. Visibility first. Comparison second. www.planetgeek.ch/2026/06/01/b... #dotnet #performance 010
Daniel Marbach @daniel.openplace.net · 08/06/2026The first benchmark I wrote looked deceptively easy. A class. A few attributes. A method. The hard part isn't writing benchmarks. It's knowing what deserves one. Profiles identify. Benchmarks validate. Production teaches. www.planetgeek.ch/2026/05/27/s... #dotnet #performance 020
