Solving the ext3 latency problem Solving the ext3 latency problem. One might think that the ext3 filesystem, by virtue of being standard on almost all installed Linux systems for some years now, would be reasonably well tuned for performance. Recent events have shown, though, that some performance problems remain in ext3, especially in places where the fsync() system call is used. It's impressive what can happen when attention is drawn to a problem; the 2.6.30 kernel will contain fixes which seemingly eliminate many of the latencies experienced by ext3 users. This article will look at the changes that were made, including a surprising change to the default journaling mode made just before the 2.6.30-rc1 release.
