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

Peng
