`relatime` is the default on many distros, and has long been "best-practice" for first pass Linux performance turning.

  MOUNT(8)       
       relatime
           Update inode access times relative to modify or change time. Access time is only updated if the previous access time was earlier than or equal to the current
           modify or change time. (Similar to noatime, but it doesn’t break mutt(1) or other applications that need to know if a file has been read since the last time it
           was modified.)

           Since Linux 2.6.30, the kernel defaults to the behavior provided by this option (unless noatime was specified), and the strictatime option is required to
           obtain traditional semantics. In addition, since Linux 2.6.30, the file’s last access time is always updated if it is more than 1 day old.
