* perf: break early after parsing required meminfo Also a match statement for compiler magic. * perf: pre-allocate strings when reading files * refactor: remove duplicate .to_string() * perf: try to print everything in one syscall println! sends a syscall for each line. * perf: get rid of duplicate uname syscall * perf: simplify first letter capitalization * refactor: directly use key in match statement
