Hello all, this is something I have long wondered about but have been afraid to ask.
When my system is chewing away on builds, the disk I/O write access pattern of my ext3 root filesystem (using CFQ, Intel SATA controller, hard disk) when visualized by GNOME System Monitor clearly shows a repetitive landscape of large peaks, 5 seconds apart, which not much activity inbetween. I understand that's due to the ex3 journal commit interval (defaults to 5 seconds). But why isn't the filesystem continuously committing only that part of the journal that is older than 5 seconds? I would then expect the write requests to be smoothened over time, which can only be good in terms of performance and low latency.
