Editing XFS (section)

===Historic Disadvantages===
* Metadata operations in XFS were slower compared to journaling file systems implemented later and designed to work with much larger logs resulting in, for example, slower performance with operations such as deletions of large numbers of files. However, a new XFS feature implemented by Dave Chinner and called ''delayed logging'', available since version 2.6.39 of the Linux kernel mainline, is said to resolve this;<ref>{{cite web |title= Improving Metadata Performance By Reducing Journal Overhead |date= December 23, 2010 |work= XFS.org wiki |first=Dave |last=Chinner |url= http://xfs.org/index.php/Improving_Metadata_Performance_By_Reducing_Journal_Overhead |access-date= November 6, 2011 |archive-url= https://web.archive.org/web/20111006152854/http://xfs.org/index.php/Improving_Metadata_Performance_By_Reducing_Journal_Overhead |archive-date= October 6, 2011 |url-status= live }}</ref> performance benchmarks done by the developer in 2010 revealed performance levels to be similar to [[ext4]] at low thread counts, and superior at high thread counts.<ref>{{Cite mailing list |title=Re: PATCH 0/12 xfs: delayed logging V6 |first=Dave |last=Chinner |url=http://oss.sgi.com/archives/xfs/2010-05/msg00329.html |mailing-list=XFS Mailing List Message |date=May 24, 2010 |access-date=November 6, 2011 |archive-url=https://web.archive.org/web/20111205021317/http://oss.sgi.com/archives/xfs/2010-05/msg00329.html |archive-date=December 5, 2011 |url-status=live }}</ref>
