%META:TOPICINFO{author="EstherF" date="1106329904" format="1.0" version="1.8"}% This topic is a place to collect information on AFS performance measurements and tools. %TOC% --- ---++ Tools ---+++ Andrew Benchmark This old and venerable suite has been used many times. It is mentioned in the [[https://grand.central.org/twiki/bin/view/AFSLore/AdminFAQ#3_18_What_is_the_Andrew_Benchmar][FAQ]]. --- ---+++ afsfsperf (low-level fileserver performance tester) [[ArlaAFS]] comes with a tool called afsfsperf, apparently available as part of their release. afsfsperf is a small programm that acts like an minimal afs-client to observe the performace of the fileserver. For relevant numbers you need to run your instance of afsfsperf on a machine that is at least as fast as the fileserver. --- ---+++ PostMark A [[http://www.netapp.com/tech_library/3022.html][NetApp paper on PostMark]]. The numbers below were made with version 1.53 of PostMark from NetApp.
Older versions of PostMark output wrong results for the number of "files deleted"!!
Here is version [[http://www.slac.stanford.edu/~alfw/postmark-1.53.c.gz][1.53 of PostMark]] Jeffrey Katcher sent me. --- ---++ Measurements ---+++ AFS vs NFS A chart showing scalability is in the [[https://grand.central.org/twiki/bin/view/AFSLore/GeneralFAQ#1_11_How_does_AFS_compare_with_N][FAQ]]. --- ---+++ Afsfsperf collection A large collection of information. All numbers done with afsfsperf from the [[ArlaAFS]] package. Varios of OS'es and filesystems benchmarked. http://www.e.kth.se/~jimmy/afsfsperf/afsfsperf.html --- ---+++ Solaris x86 Inode vs Red Hat Namei on same hardware From a [[https://lists.openafs.org/pipermail/openafs-info/2003-April/008916.html][message]] 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 [[PerformanceWork#PostMark][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
