  • Underestimated answer, thank you! I thought that browsing is a simple task that doesn’t benefit from multiple cores. Commented Jul 11, 2020 at 18:17
  • @AlexeiSavitsky - Well, to be honest, I'm not an expert in browser technology so I don't know how much they've actually done. I know for sure that each tab gets their own process these days. But layout calculations are pretty complicated too and drawing is done with hardware acceleration, so there certainly are opportunities for multithreading. Commented Jul 11, 2020 at 18:20

    +1 Multithreaded software is very common. When performance matters, a serious software developer will usually at least consider using multithreading as part of an optimization, and modern programming frameworks make it relatively easy. Also, much of today's software is web based; such software is effectively multithreaded automatically, because web servers are multithreaded. You don't need to multithread your web software (although it can sometimes help for long running operations) if your web server is already using multithreading to more efficiently serve multiple concurrent users.

  • I just checked my browser (Chrome). I have currently 1 tab open, but there are 7 chrome processes open (leftovers from previous tabs and the frame) and they each have anywhere between 6 and 32 threads. I don't know what they are used for, but it's obvious that Chrome does rely on multithreading. Commented Jul 11, 2020 at 21:06
  • Correct. It's very unlikely to run software on a single thread operating system. The reason this might not get an appropriate amount of votes is because this community is biased towards programming, where users are delegated a single thread from multiples that have been previously split.
