opnsense build using not using all cpu cores

[none]

Hi,

I build arm64 images for opnsense and this week I begun building for 26.7 family. Usually ports build takes 20 to 24 hours, but it is now over 3 days and not close to end.

Has the change to FreeBSD 15.1 demanded special config to use all cpu cores? FreeBSD can see all 8 cores:

but the ports build uses only one :(

If anyone have any hints on how to change it :)

thanks,

The ports build one by one. Some ports use multiple CPUs, some don't. Not looking into changing this.

Poudriere exists if you want to use it, but it's overloaded for our use case.

Thanks for the answer.

My usual build time for it all was about 36h. Now its way more, and the box is the same. I am looking for the reason :)

I found 15.x to be somewhat slower on IO in general. Noticed while installing images mostly. I'm not sure what to do about that.
