Jens is also the author of the blktrace utility and kernel parts, which provides a way to trace every block IO activity in the Linux kernel. blktrace exists in 2.6.17 and later Linux kernels. To facilitate his block layer work in the Linux kernel, Axboe created the flexible IO tester (fio) benchmarking and workload simulation tool.[3] fio is able to simulate various types of I/O loads, such as synchronous, asynchronous, mmap, etc., as well as specifying the number of threads or processes, read vs. write mix, and various other parameters. fio was used to set the world record in December 2012 for the highest number of I/Os-per-second (IOPS) in a single system.[4]{{Notinsourcegiven|date=January 2017}} In May 2010 Axboe joined Fusion-io after leaving Oracle Corporation.[5] He announced on a mailing list on Friday, January 24, 2014 that he was leaving Fusion-io after 3.5 years to join Facebook.[6] References1. ^Interview: Jens Axboe {{webarchive|url=https://web.archive.org/web/20070311003900/http://kerneltrap.org/node/7637 |date=2007-03-11 }} 2. ^[https://events.linuxfoundation.org/jls06b Jens Axboe, Oracle] {{webarchive|url=https://web.archive.org/web/20121014162751/https://events.linuxfoundation.org/jls06b |date=2012-10-14 }} 3. ^fio git repository 4. ^[https://lkml.org/lkml/2012/12/15/26 Jens Axboe, Re: AIO performance improvements and cleanups version two, LKML, December 15, 2012] 5. ^{{cite web|url=http://axboe.livejournal.com/3616.html |title=Last Day at Oracle |last=Axboe |first=Jens |date=2010-05-31 |deadurl=yes |archiveurl=https://web.archive.org/web/20120416181646/http://axboe.livejournal.com/3616.html |archivedate=2012-04-16 |df= }} 6. ^{{cite web|last=Axboe|first=Jens|title=Leaving Fusion-io|url=http://lkml.iu.edu/hypermail/linux/kernel/1401.3/00257.html}} External links
