| IV.E.1
| Test performance with large numbers of small (<4k) files
| addhoc tool
| In progress
| Bull
|
| While most NFS functionnalities are not affected by the number of files (1 000 000 of empty files), some bash functions are not responding : ls (answer take more than 15 hours). This question will be splited in sub topics soon.
|
| IV.E.2
| Test performance with a few very large (>1G) files
| IOzone
| Open
| Bull
| Goals need some clarifications
