See the test results for both "ls" and "ls -la" commands: # time ls -la | wc -l 31767 real 0m2.967s user 0m0.627s sys 0m0.689s # time ls | wc -l 31764 real 0m1.508s user 0m0.262s sys 0m0.082s Comparing with the results in my previous email, does it indicate that GFS is not designed for sharing huge number of small files? I heard that GFS is originally designed for sharing small number of larger files. Is that true? If so, could you please kindly suggest a file system which can handle huge number of concurrent requests on many many number of small files? Thanks for your interest.
