Hi
All,
Are there any kernel
parameters could improve system performance in area of IDE access and
file system?
In our embedded
system, We have disabled the read ahead for ide device (Compact Flash), mounted
the CF device with "noatime, sync" option. At least disabling the read ahead has
improved the RT tasks not to miss their scheduled slot (10
msec).
We have created ext3
file system on CF, are there any kernel parameters that improve the file system
performance, I/O scheduler, etc...?
We do not care
if the data rate is slower for CF, just better
performance.
Our Linux version is
2.6.11.
Many thanks in
advance,
Bizhan
