Filebench - A Model Based File System Workload Generator


Running a set of workloads with BenchPoint
------------------------------------------

$ mkdir mybench
$ cd mybench
$ cp [prefix]/filebench/config/filemicro.prof mybench.prof

 or

$ cp [prefix]/filebench/config/filemacro.prof mybench.prof

$ vi mybench.prof
<edit params>
set your stats dir to where you want the logs to go...

$ runbench mybench

$ browse the index.html in the stats dir



Example individual varmail run:
-------------------------------

filebench> load varmail

Current "filemacro" Workloads:
- varmail		(file read/random append-write mail server benchmark)
- bringover		(copy fileset of random sizes)
- oltp  		(database simulation)
- webserver		(reads on fileset of random sizes + random append logfile write)
- webproxy		(reads, writes, creates, deletes  on fileset of random sizes)
- fileserver		(reads, writes, creates, deletes  on fileset of random sizes)

Current "filemicro" Workloads:
- singlestreamread	(sequential read from a large file)
- multistreamread	(multiple stream sequential read from large files)
- randomread		(random fixed size reads)
- randomwrite		(random fixed size writes)
- createfiles		(create and allocate files in a directory tree)
- deletefiles		(delete files in a directory tree)
