you can look at the syscalls used by running it through strace and
looking to see what it's doing.
$ strace -Ttf sh -c 'echo *.txt'
$ strace -Tt find -name '*.txt'

that said, this is the coreutils group which doesn't maintain either
`find` or `sh` or `bash`, so you'll want to try one of the other
groups.  or talk to the glusterfs group to see what aspect their fs
is not as good at.
