Hop reduces the number of syscalls necessary to both read and check for the existence of multiple files nested within a shared parent directory. You read from one file to get all the information you need instead of reading from N files and N directories. Can’t easily mount virtual filesystems outside of Linux. However, Linux supports the copy_file_range syscall which also makes it faster to copy data around than doing it in application memory
