Run with min 1 cpu core left to the user

[davsclaus]

If you have 8 cores on a computer, then mvnd will utilize them. However if you work on other things then your computer can be a bit sluggish if mvnd is heavy building.

It would be good to tell mvnd to only use max cpu - 1 so I have 1 for my self.

Yes, mvnd runs the daemon with -T1C by default, but you can pass any any other -T if you like, see https://cwiki.apache.org/confluence/display/MAVEN/Parallel+builds+in+Maven+3

If you want to make it permanent, you could alias mvnd in your .bashrc, something like the following:

# Mac
alias mvnd="mvnd -T$(($(sysctl -n hw.ncpu) - 1))"

# Linux 
alias mvnd="mvnd -T$(($(nproc --all) - 1))"

I am fine with the current default. What do others think?

Okay whatever mvnd does by default does not feel like it leave any cpu resources left for me. I cant hardly browse my mail on in a web browser because cpu is 98-100% when you for example does a full rebuild of Apache Camel - runs for 20 min+.
And the parallel builds goes up to 8, and I have 8 cores.

So maybe make it run with -2 core.

And maybe make that -T option configureable in your general configuration file. Then I can hardcode it to 6.

I agree that -T1C is too much, I now often run with -T0.5C which sounds more reasonable. We could change the default to this value... Le mar. 20 oct. 2020 à 09:30, Claus Ibsen <notifications@github.com> a écrit :
