Parsing a string is significantly faster than disk io, so this is not an issue unless you are reading minuscule amounts of data.

- tlb 3y agoThat was once true, but not on most modern systems with SSDs. Cheap NVMe SSDs can sustain over 1 GB/s, which only a highly optimized SIMD parsing library can exceed.
- fooker 3y agoYou are missing the point. The format string is tens of bytes, parsing it is fast no matter what compared to reading large amounts of data.
- tlb 3y agoAh, I thought you meant the speed of parsing the payload didn't matter (scanf performance was also discussed). Yes, parsing the format string in printf or scanf isn't a big deal.
