While back 2014 - I joined a company that just implemented NS ( done by Explore consulting - AKA RSM) had over 50 client and user event scripts for SO, too many filters via scripts to name a few. Jut to load the form used to take 120+ sec and at that time they didn't offer suitecloud plus either. Also had labourcost rollup scheduled script that calculated labourcost across 11 subs on projects and bill them to sub properly, used to take 8-10 hrs to run, and if there was any exception it sued fail and start up again from beginning. My job was to stabilize it - and that was a tall order.
