Question: "Hi there. I know it's been 5 years but I'm wondering why the performance counter feature never made it into a full release.My answer: "It was a cool concept, but one snag that I hit is that there's a limit on the number of simultaneous hardware counters the processor can keep track, and the htop UI would naturally lean you towards going overboard with it (several columns x every process), so in the end it wasn't a great fit, even though it made for a cool proof-of-concept demo. Sometimes the PoC ends up disproving the concept, I guess! The tabbed interface I created for this feature did get into htop 3, and I think that was actually the largest amount of code from this project, so all was not lost!"</a></label><br><a href="https://files.mastodon.social/media_attachments/files/110/787/409/077/263/371/original/e5174299db25847e.jpg" rel="external">https://files.mastodon.social/media_attachments/files/110/787/409/077/263/371/original/e5174299db25847e.jpg</a></li></ol></footer></blockquote>
