How can you talk about Solaris performance without mentioning dispadmin?
- brendangregg 13y agoLinux has CPU scheduler tunables via CFS/cgroups. dispadmin allows fine tuning of the dispatcher table, but I've never seen that provide significant or consistent wins for production (and I've had use cases where it seemed possible in theory, and dtrace'd dispatcher queue latency, but dispadmin didn't really help.) I might mention dispadmin in a 5 day talk. :)
