There is not enough information here to begin considering your problem report. http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F I'm not even sure I understand what you have stated so far; you see the RPS (requests per second) increase after the system has been up for one hour, is that correct? In any case, we aren't nginx experts here; you will need to do more investigation to find out what is actually happening at the filesystem level before we can be of much help, I think. -Eric On 12/21/15 1:09 AM, Linpeimin wrote: > Hello , we use xfs file system to test nginx , I found the power-on > reset , within the first one hour nginx relatively poor performance, > and after one hour , re- test , performance result( RPS) of dynamic > pages has improved.If we change the file system into ext4, you do not > have this phenomenon , after the start,RPS performance has remained > stable. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
