I will pick up the topic of fio tools and also introduce a tool based on fio that is implementing a recent SNIA specification: * Solid State Storage (SSS) Performance Test Specification (PTS) - http://www.snia.org/tech_activities/standards/curr_standards/pts I was looking for an open source tool implementing this specification, but I could not found one. Therefore I have written a performance tool implementing the standard, in Python using fio: * TKperf - http://git.thomas-krenn.com/TKperf_v1.git/ * TKperf is starting a test for a device and generates plots and a pdf report: - http://www.thomas-krenn.com/de/wikiDE/images/e/e5/TKperf-Report-IntelDCS3700.pdf (a report for the recent Intel Data Center SSDs) * More information (video, slides, wiki article) - http://www.thomas-krenn.com/de/wiki/Event-News:_LinuxTag_2013_SSD_and_HDD_performance_testing_with_TKperf - http://www.thomas-krenn.com/de/wiki/TKperf > > I hope this work will have some interest for the fio project or > > maybe some > > other users. My intention is also to increase the degree of popularity for fio, as it is awesome!
