Summary: Poor perfomance
Product: File System
Version: 2.5
Kernel Version: 3.0.0
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: XFS
AssignedTo: xfs-masters@xxxxxxxxxxx
ReportedBy: anz_ul@xxxxxxx
Regression: No
With big partition (>60Tb) have some problem with perfomance. After not long
use (10 or 12 days) reading speed down for 50 Mb/s. Normal speed from other
disk (<40Tb) 260-300 Mb/s. After, when we delete partition 61 Tb and create new
31 Tb everything is fine and speed is 260-300. May be I must do something for
better perfomanve, but why when I create a partition reading speed is normal
260-300 Mb/s. But no prublem with write speed in all partition 260-300 Mb/s
