Why is `find -name '*.txt'` much slower than '*.txt' on glusterfs?

[Peng Yu]

Hi,

There are ~7000 .txt files in a directory on glusterfs. Here are the
run time of the following two commands. Does anybody know why the find
command is much slower than *.txt. Is there a way to change the api
that `find` uses to search files so that it can be more friendly to
glusterfs?

$ time echo *.txt > /dev/null

real    0m2.206s
user    0m0.039s
sys     0m0.056s
$ time find -name '*.txt' > /dev/null

real    0m18.558s
user    0m0.317s
sys     0m0.663s
