Hello,
It was explained already a couple of times since October 2005 (search the archives).
In short: if you are buying new hardware buy dual core machine. Why?
Even if apps do not use multiple threads, running 2 or more apps (who runs only 1 app on Windows ???)
is way smoother on dual core. You will never see system "freezing" when some program
is busy processing. For this alone it is worth buying.
As for AB - it was discussed earlier. Most parts use single thread.
Some RT plugins use multiple threads (eSignal, IQFeed), AmiQuote uses multiple threads,
list controls use additional thread.
I was making experiments on parallelization of AFL engine itself but it turned
out that single thread is faster because tasks are short, can be highly-pipelined using proper
code writing (removing jumps from assembly code) and no time is wasted on context switching
and thread synchronization.
The only part that is suitable for SMP is optimization and it will be done sometime in the future.
Best regards,
Tomasz Janeczko
