Let's write some iRules together!
summary
Live coding with iRules in Visual Studio Code, showing concrete fixes and measurements: why global variables demote CMP and force single‑core TMM, how to move constants into rule init/static namespace, why use after to delay per‑connection instead of blocking loops, a comparison of seven IP‑match methods with equals plus mask as the most performant, and practical shared‑state options (shared var, table/session) including the traffic‑group limitation. Practical snippets and toolbox links are shown and tested.
