Subject: [PATCH] update readahead value for better performance
|
||||
|
||||
Description: dasd,zfcp: Add udev rule to set increased "default max readahead"
|
||||
Symptom: Sequential read performance on disks is not as good as it could be.
|
||||
Problem: The current "default max readahead" defined by the kernel is too
|
||||
small for s390 (128 kb).
|
||||
Solution: Add udev rule to set a better default value (512 kb). This will
|
||||
increase sequential read performance up to 40%.
