+
+This old and venerable suite has been used many times. It is mentioned in the [FAQ](https://grand.central.org/twiki/bin/view/AFSLore/AdminFAQ#3_18_What_is_the_Andrew_Benchmar).

+
+[[Arla]] comes with a tool called afsfsperf, apparently available as part of their release.

+
+A [NetApp paper on PostMark](http://www.netapp.com/tech_library/3022.html).
+
+The numbers below were made with version 1.53 of PostMark from [[NetApp]]. <br /> Older versions of PostMark output wrong results for the number of "files deleted"!!<br /> Here is version [1\.53 of PostMark](http://www.slac.stanford.edu/~alfw/postmark-1.53.c.gz) [Jeffrey Katcher](mailto:katcher@netapp.com) sent me.

+
+From a [message](https://lists.openafs.org/pipermail/openafs-info/2003-April/008916.html) on the [[OpenAFS-Info]] mailing list:
+
+> I was wondering how Solaris x86 would be doing as AFS fileserver compared to Red Hat 7.3 Linux on the same hardware.
+>
+> I've conducted some benchmarks using [[PostMark|Main/PerformanceWork#PostMark]] and arla's afsfsperf to get an answer (not _the_ answer!) to this question.
+>
+> I've used [[OpenAFS]]-1.2.8 with inode and namei interface on Solaris with non-logging and logging file system for the /vicepa partition.
+>
+> On Linux I've used [[OpenAFS]]-1.2.8 (namei only) with ext2, ext3, reiserfs v1, and reiserfs v2 for /vicepa.
+>
+> The results are available under [http://www.slac.stanford.edu/~alfw/AFS\_bench2.html](http://www.slac.stanford.edu/~alfw/AFS_bench2.html)
