Recently I came across with the lack of information about Mathematica performance in different machines, even though there's a benchmark process already implemented, the WolframMark. Data available includes only 15 old machines and I couldn't find more online.
As a lot of people consider Mathematica's performance when buying a computer I think it'll be very useful to create a database that includes benchmark results from different processors and operational systems.
It's very simple to ask people to run the benchmark in their computers, my suggestion is to ask them to restart the Kernel (two clicks procedure), run
and send the output with some key-specs like processor's model, number of cores, frequency and RAM.
If we create such database we can provide useful information about what one should consider when buying a machine and it can be hosted in a website or sent to Wolfram.
I think it's pretty easy to gather data since we can ask our friends and even send institutional/corporate emails. In conclusion, are there people interested in contributing for this project?
OBS: I think WolframMark seems reliable enough to compare machines. After 100 benchmark results my 3th-gen-i3 score was 1.166(9) and one colleague's 5th-gen-i7 got 1.38(4).
