NFS performance troubles 2: What actually happened
A while ago, I wrote about VictoriaMetrics and, by extension, Grafana performing poorly, and placed the blame on NFS not being a good storage backend for most types of databases due to the requirement for reliable, granular, low-latency writes. While that’s objectively true, I didn’t use the database heavily enough for that to matter. It turned out that the problem was of entirely different nature all along.
NFS performance troubles
Recently, I started having issues with self-hosted services running slow, despite ample memory reserves and load averages that were fractions of the number of available CPUs. That got pretty annoying, especially given that I recently set up Grafana alerts that send Telegram notifications when one of the services is slow or unreachable.
