For the Super User Questions of the Week #15 the highest voted answer was How much speedup does a hyper thread give? (in theory).
While we should be looking at what theoretical boost Hyperthreading can give I believe we also need to bolster that and physically quantify the "real-world" boost that Hyperthreading gives. To that end I would like to gather opinions and programs that are suitable for proving whether this feature is useful or not.
At the moment I can see the following tests being valid
7-Zip using a large file collection & 8 threads
Handbrake H.264 encoder (does anyone know if there is an accepted "standard" video to convert? Probably not necessary so long as the tests are consistent...)
As I see it we can also gather some information from http://www.cpubenchmark.net and compare CPUs with and without Hyperthreading to get some vague correlation.
If anyone has any good multithreaded programs, appropriate single-threaded applications or even just best-practice test procedures I'd be grateful if you could let me know.
