 |
|
I'm using an Acer A515-57 laptop. Processor is i5-12450H and 16G DDR4.
Ive experimented with MAKEOPTS in /etc/portage/make.conf and emerging app-misc/mc
With Make set to 8 jobs and a load average of 9, mc compiles in:
real 0m44.099s
user 1m13.009s
sys 0m19.499s
With make set to -j8 and -l3 I get a faster compile time of
| Code: | | time emerge --ask app-misc/mc |
real 0m49.376s
user 0m55.429s
sys 0m15.577s
I don't know if this a good or bad result for this hardware, but I have conky running on my desktop, and it never uses more
than 2G RAM when mc is emerged.
Below is my /etc/portage/make.conf

Hmm ... 44 seconds is less than 49 sec. ... so, this is expected and correct (dont count/add the other values; you dont need them)
