amd processors seem slow at running configure?
My new AMD a8-3850 takes 77 seconds to run wine's configure script. (Using -C cuts the time by 40 seconds.) Austin's Phenom II X4 940 takes 61 seconds. My i7 takes 32 seconds... but even the lowly e7300 only takes 38 seconds. The same seems to hold for doing builds with ccache; AMD fares poorly there somehow compared to similar intel chips. Does anyone have an AMD-based system that can run configure in under 40 seconds?

My AMD Phenom(tm) II X6 1055T Processor runs it in about 30 seconds.

The Llano APUs lack L3 cache which can make them quite a bit slower than AMD Phenom CPUs. Also make sure that your RAM really runs at high clock speeds. Roderick

It might be related to frequency scaling. I have a Phenom II X4 945 and configure runs in 29 seconds, but only when using the performance governor. When using the default ondemand governor it runs in 59 seconds, similar to what Austin got. It would be interesting to know how the i7 fares when using the performance governor.

Good call! After doing for cpu in `seq 0 3` do; sudo cpufreq-set -g performance -c $cpu; done the a8-3850 runs configure in 37 seconds!

On the i7, after doing "./configure" once to warm up, ondemand gives 31 seconds, performance gives 23 seconds. So it's not AMD-specific. 'conservative' gives 26 seconds, halfway between the two. - Dan

my q9300 isn't affected by this much; either way, it takes 32 to 37 seconds to run configure there.

Handy tip, Dan. Thanks :)
