Extreme cpu and memory usage

[phanirithvij]

Gup updates all packages at once which when there are many (eg ~70 in my case) takes up all the ram 8GB and all cores are at 100% at 89°C. As it spawns ~1900 threads. Thus it is unusable and I had to force quit linux.

Maybe limit it to the number of cores like make -j8. i.e. provide a -j cli arg for people who need it. And set default value to no. of cores.

Thank you for your bug report.

The gup command was designed to create as many goroutines as the number of binaries existing in $GOBIN.
However, in an environment with a large number of binaries, the CPU load was abnormally high.

Therefore, from Ver. 0.19.0, the upper limit of the number of goroutines created is set to the number of CPU cores.
The upper limit for the number of CPU cores used can be changed with the "--jobs" option. The default is the maximum number of CPU cores.

Thanks for the quick fix, I will test it and report back.

Works! Hit 3GB ram usage max, 59°C (idle is 37°C), updated in 8m20s
