IV.A Comparison of NFSv4 vs. NFSv3 for common use cases

ID test tool test status owner notes
IV.A.1 Time to perform sequence of unique read/write operations Iozone Open Bull Done by Bull in 2004
IV.A.2 Time to perform sequence of cacheable read/write operations Iozone New
IV.A.3 Random reads/writes/opens from many clients to one server Iozone Open Bull Done by Bull in 2004
IV.A.4 Industry standard loads SpecSFS, Specweb99 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 Iozone New Bull
IV.A.7 Metadata - open/close intensive workload Iozone New Bull
IV.A.8 Metadata - directory scanning Iozone Open Bull
IV.A.9 Metadata - create/delete Iozone New Bull
IV.A.10 Metadata - changing attributes (chown, chmod) while dir scanning IOZone New Bull

IV.B NFSv4 on TCP vs. RDMA

ID test tool test status owner notes
IV.B Compare latency, throughput, etc. of NFSv4 on TCP vs. RDMA New Only prototypes exist currently; possibly will be more fully implemented by end of 2005

IV.C Test performance on different local filesystems

ID test tool test status owner notes
IV.C.1 Analyze whether file system choice affects performance Iozone Done Bull NFSv4 performances do not depend on the local file-system used
IV.C.2 Test performance with Ext2 on server with metadata /acls IOZone/FFsB
IV.C.3 Test performance with ext3 on server with metadata / acls IOZone/FFsB New
IV.C.4 Test performance with Reiser3 on server with metadata / acls IOZone/FFsB New
IV.C.5 Test performance with xfs on server with metadata / acls IOZone/FFsB New
IV.C.6 Test performance with jfs on server with metadata / acls IOZone/FFsB New
IV.C.7 Test performance with Reiser4 on server with metadata /acls IOZone/FFsB New
