TIL that software (especially #scripting runtimes like #Python, #Perl, and #NodeJS) running in #Alpine #Linux containers is often slower than in other distros like #Ubuntu. This is despite Alpine being faster on startup and often vastly more efficient with CPU, memory, and storage.
It mostly comes down to Alpine’s use of musl libc rather than #GNU’s glibc. musl is optimized for minimalism, not raw performance. Also, the Alpine packages are often not compiled with as many optimizations.
