it's a poor customer experience and I immediately disabled the auto-completion due to the increased startup time

[brandonskiser]

Hey, thank you for the feedback! I agree, we need to investigate how to decrease the startup time.

I have two MacBooks - M1 (Sequoia 15.2) and M3 (Sequoia 15.3). Both have bash 5.3 as default

The M1 one opens a new terminal window in less than a second, the M3 one opens a new window in ~3-4 seconds.

I tried to pinpoint the issue to configuration or something else, but the only major difference between these two laptops is that M4 (the slower one) has Rosetta 2 installed.

I hope this help to debug the issue. Thanks
