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
You'll want to use the "No-op" scheduler. Also, you can add
"nodiratime" to your mounting options.
