Disappointed by new M3 Air 13”/16/512 performance. Lags while multitasking. Help! :|

Hi nice people of this sub, I’ve been nerdy about tech for maybe 15 years, and have gone the whole arc from android/pc-gamer teen (who *wants* save money) to Apple ecosystem adult [new iPhone16pro, MBA, and a 2yo iPad Air] Not gonna lie, it’s insane to own any of it and pretty damn fun! However, I’m particularly disappointed by my MBA’s performance. Is it supposed to lag while doing the following together: extend display to iPad, run software for external keyboard+mouse, run 6-7 pdfs, 40-50 safari tabs, 2-3 pages documents (I switched to it from docs for the performance smh), Spotify, and the occasional full screen video? Am I supposed to close docs and software as I go? Should I end the day putting all my work in little folders? (The laptop is externally cooled but heats up here and there to the 90s) The lag is actually insane if I do the above. The mouse, typing, switching between windows, all lags. Anybody else experience this? Forgive me for the aggro, but is this really what 1400 US buys you? It’s my first big money purchase (in my life xd) and I was truly into believing the Apple silicon hype when I heard about it (around the same time GPUs disappeared for AI) Not tryna be a hater or too disgruntled lol. Any help or context to any of this would help. Thanks a whole bunch for hearing me out :) Tl;dr: MBA performance issues while multitasking, annoyed, help. P.S: I will check activity monitor soon but I don’t see anything there except for Pages.
