My windows with corporate crap is sometimes 2000x slower than without corporate crap. And consistently 10x slower than an M3

Don’t worry, my new M4 doesn’t feel much faster either due to all the corporate crapware. Since Windows Defender got ported to Mac it’s become terrible in I/O and overall responsiveness. Any file operations will consume an entire core or two on Defender processes.

My personal M1 feels just as fast as the work M4 due to this.

I was impressed with my M4 mini when I got it a year ago but sometime after the Liquid Glass update it is now: beachball… beachball… beachball… reboot… beachball… beachball… Reminds me of the bad old days of Win XP.

How much RAM do you have? That seems to be the main thing that slows down my MacBooks (original launch-day 16GB M1 MBP and 32 GB M2 Pro). The M1 CPU is finally starting to show its age for some things, but the M2 Pro is really only RAM limited in perceived speed for me.

RAM. You must have 16 GB or more. And for serious work now, I’m looking at 32 GB or more.

I haven't had a laptop with less than 32GB of RAM in about 15 years. RAM is extremely useful for some workloads.

Mine has 48GB.

Those sound like very well tested numbers, founded in reality /s
