Hello , we use xfs file system to test=
 nginx , I found the power-on reset , within the first one hour nginx relat=
ively 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 rema=
ined stable.

At present it is difficult for us to explain th= is phenomenon.I hope I can get your support and answers , very grateful !

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@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
