Hi Minh,
> Thanks to Rob and Yann for the architecture info. For future reference,
any optimization is very welcome. But for people who don't live on trac, a
summary including timing and memory statistics as well as system
architectures can be very useful. Of course any developer who has an
account on sage.math can get the timing and memory statistics. But
sage.math is not a regular PC or laptop; it's a powerful multi-core (over
20 cores, I think) machine with over *100* GB of RAM.
The relative improvement will be identical, i.e. the fact that there are
many core and a lot of RAM does have zero impact on CPU bound improvements
like this. Indeed, due to the nature of the CPU and memory topology
sage.math might actually see less of an improvement in certain cases.
Cheers,
Michael
