Khem  was asking if anyone had seen a >30% difference in build time for
qemuarm compared to other machines. I don't when building on my system:
rmacleod@yow-rmacleod-lx3 b/c-i-m-x86 $ cat x86
real    43m29.142s
user    0m19.887s
sys     0m4.110s
rmacleod@yow-rmacleod-lx3 b/c-i-m-x86 $ cat arm
real    42m58.185s
user    0m19.546s
sys     0m3.867s
This machine is relatively isolated in that there are no other users.
The arm build was done second and I didn't pre-populate the downloads
but so that may account for the 30 second difference.
I wasn't using sstate for either build.
Thanks for this infor Randy, really appreciated, I think I will also look at the h/w angle.
