But if we can get that 3 day process into a 3 hour process (e.g. > I've only got about 4GHz worth of ARM cores, but about 40GHz worth of > x86-64 cores), then the problem is at least transitioned from the realm > of unworkable into the realm of slow. Well there's nothing stopping people from doing that themselves. I've tried QEMU emulation on an IBM x3850x5 I have at work with 64 2.8 ghz threads and 256 GB of RAM. Its still slower than the real arm boxes. > Once you know it builds and works, waiting for 3+ days so bad because at > least you know something usable will come out of it. Believe me I am painfully aware of that. I have got gcc to compile on one of the ARM boxes in mock. Using koji on the same device it doesn't compile and I have no idea why so its still not a guarantee it seems, very unfortunately!
