Arrayformula and sheet slowdown

Ever since I got somewhat comfortable with Arrayformula I have been using it everywhere and can’t imagine how I survived without it for so long.

My question is if it affects the performance of the spreadsheet that much. My calculations would be simple, limited to COUNTIFS, SUMIFS, IF conditions based on multiple columns etc.

Would appreciate some advice on how much is too much.

Simple formulas seem to run pretty quickly, so as long as the sheet is updating quickly, I would think you would be fine. I use several formulas and queries and I haven’t noticed any lag. I’m not working with massive data sets, but I’m also running some scripts and and haven’t run into any speed issues yet.
