| Done by Bull in 2004
|
IV.A.4
| Industry standard loads

| New
|
| Tools does not exist.
|
IV.A.5
| Time to read file from beginning to end and then rewrite it
| IOzone
| In progress
| Bull
| Part of IOZone standard tests
|
IV.A.6
| Time for appending info to a log file sporadically over time

| New
| Bull
|
|
IV.A.7
| Metadata - open/close intensive workload
| Iozone
| New
| Bull
|
|
IV.A.8
| Metadata - directory scanning
| Iozone
| Done
| Bull
| Directory scanning over NFSv4 is analysed here. Time to stat a directory is O(n²) where n is the number of files in the directory.
|
IV.A.9
| Metadata - create/delete
| Iozone
| New
| Bull
|
|
IV.A.10
| Metadata - changing attributes (chown, chmod) while dir scanning

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 (2 000 000 of empty files).
|
*IV.E.1
*Sub topic 1
| Test performance with large numbers of small (<4k) files - stat function ; empty files -
| addhoc tool
| Done
| Bull
| Stat answer is O(n²). More details here
|
IV.E.1
*Sub topic 2
| Test performance with large numbers of small (<4k) files - Open function ; empty files -
| addhoc tool
| Near done
| Bull
| Open function is O(n). There is a bottle neck for n=1620000. More details here. Comparisons with local file system and NFSv3.
|
IV.E.2
| Test performance with a few very large (>1G) files
| IOzone
| Open
| Bull
| Goals need clarifications: are we manipulating files (acl/metadatas/moving...) or reading/writing files?
|
IV.E.3
| 4-16 clients generating high load on 1 server in lab environment
| Mail/user dir
| New
| Bull
|
|
IV.E.4
| 2000-5000 clients on 5-10 servers in production environment
| Clusters
| New
| NetApps
|
|
IV.E.5
| NFS "Cluster" scenario with 1000+ clients and several servers
| Film industry, HPC or visualization workload
| New
|
|
|
IV.E.6
| NFS front end with cluster backend; 100+ clients
|
| New
|
|
|
IV.E.7
