pm8001 performance degradation?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Jack Wang and Lindar Liu,


I am running the pm8001 driver (on applicable hardware including a
several core SMP server).

When I run on an older kernel -- e.g. 2.6.34.7 -- I get about 73Kiops
via an fio test.

When I run a current kernel -- e.g. 2.6.39.2 -- on the same system and
same storage I get about 15Kiops running the same fio test.

Perhaps something has changes in the kernel that is not being accounted for?
Are you two still maintaining this driver?


Regards,
David
