      I felt the 21st century theme really worked. Doing things thoughtfully with standards and consensus while trying to get them right was a theme. Languages and ways of using them and open design have nade such progress in the last decade.

      When @steveklabnik talked about c10k he didn’t mention the 10k lines of C it took to write it then. Maybe thats an exaggeration but not sure.

      I mean Nginx was the only comprehensive implementation of c10k for a long time and I think its over 10k loc and a few library calls in the performance serious modern languages are getting close.

      Apache 2.0 was c100k in 2002. I have the receipts!

      Yeah @steveklabnik did mention that it changed its design pretty soon (I still remember the mass switch to Nginx and the less long lasting lighttpd). I would love to see a graph of the increase. There was so much innovation in a short period.

      Oh god this took me down a rabbit hole. http://www.stdlib.net/~colmmacc/Apachecon-EU2005/scaling-apache-handout.pdf … , we could do c100k, but c27k was our actual record in production. Almost all of it was scheduler and VM tuning though ...pic.twitter.com/3j2bfSCqKO

          I forgot too that we did profiling to find the optimal buffer sizes with the best mechanical sympathy. Around 30KiB at the time. I wonder what they are now.pic.twitter.com/yZ91y7eLLG

          I'm 99% sure this quote came from @noirinp. Nóirín reviewed the paper, is in the acknowledgements section, and .... played the harp!
