upgrading to Sequoia, all worked flawlessly but port migration very very slow

[Fabien Auréjac]

Hello, after upgrading to Sequoia, all worked flawlessly without need of 
anything, but when I tried to update macports via port selfupdate, it 
asked for a migration.

All seems to be working well, but I'm quite surprised about the time it 
takes... for 500+ ports, more than 8 hours of compilation on a macMini 
M1, and it's not finished...?

On Sonoma compiling seemed to be really faster... Is this due to the 
process of migration ?

Or is it a regression of performance due to some sort of macOS 
performance or security clamping ?

Thanks
