A Qemu Comparison

Jan 30, 2024

I wanted to create a build system on my X86-64 laptop that would cross-compile apps, and then package them in the alpine *.apk format. Did I accomplish this task? Yes. Will I be using my build system? Nope.

Why?

qemu-aarch64: 
real    1h 8m 39s
user    4h 21m 47s
sys     2m 16.29s

x84_64:
real    2m 13.35s
user    11m 10.88s
sys     0m 23.99s

That’s right. In took over an hour to cross-compile and package the software. I’m still grateful that qemu exists, and to be honest the slow compilation could be the result from user error.
