[Linpeimin <linpeimin@xxxxxxxxxxxxx>]

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.

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