title: POSIX Threads vs. Win32 Threads
body: <p>I just <a href="https://stackoverflow.com/questions/5644068/why-posix-threads-are-slower-than-openmp">dipped my toes</a> into the POSIX pond and tried out POSIX threads for the first time. Until now, I'd been under the impression that there's a big architectural difference between POSIX threads and Win32 threads, but from the (admittedly little) that I tried, I didn't really see any difference.</p>
  
  <p>I'm still curious though -- what are the differences (if any) between POSIX threads and Win32 threads? Are they different fundamentally, or do they just have minor differences?</p>
