strace -o strace.log dirname -- /some/path/here Cygwin via Git for Windows 2.47.x Windows 10 I see: >3249 60966 [main] dirname 31200 time: 1736590460 = time(0x0) On average it shows between 2000-4000 duration (I'm using Cloudflare's ntp servers) which seems fishy to me, as this shouldn't be that slow?
