Maybe, but most personal user data is at some level handled by
programs written in C: database engines and operating systems.
Although I've noticed that the current trend is to focus less
on performance and more on scaling, e.g. cochroachdb is an
implementation of a Spanner like SQL database in Go.
If it doesn't scale, then it's slow no matter what it's written
in. For example SQL is slow even though it's very optimized: you
simply can't handle millionfold increase in server load and data
size with C optimizations, and that increase happens just fine.
If it's 1usec vs 1msec it doesn't matter because the user doesn't
see such difference, it it's 30sec vs 60sec it's still doesn't
matter, because both are beyond user patience. Performance
doesn't work incrementally, it just either works or doesn't, so
you're unlikely to achieve anything by making it twice as fast.
Also why Cloudflare wrote new parser? Because ragel parser was
slow. It's written in C and does all funny C stuff, but is slow.
So where's famous C performance?
