I'm wondering if anyone out there may have some suggestions on how to improve the performance of a system employing fsync(). I have to be able to guaranty that every write to my fileserver is on disk when the client has passed it to the server. Therefore, I have disabled write cache on the disk and issue an fsync() per file. I'm running 2.4.19-pre7, reiserfs 3.6.25, without additional patches. I have seen some discussions out here about various other "speed-up" patches and am wondering if I need to add these to 2.4.19-pre7? And what they are and where can I obtain said patches? Also, I'm wondering if there is another solution to syncing the data that is faster than fsync(). Testing, thusfar, has shown a large disparity between running with and without sync.Another idea is to explore another filesystem, but I'm not exactly excited by the other journaling filesystems out there at this time. All ideas will be greatly appreciated.
