Description

Hi ,

   The total lustre write throughput became lower after I transfer many small files to lustre.(about 1000000 files, 1MB per file). The write throughput seems the same even remove these small files. I have test obdfilter-survey, it also got the lower throughput performance. Do  you  have any suggestion to make the luster cleaner?   Thanks.
