It's disappointing to see how Ext4 seems to be going backwards. I know that the mount options make a huge difference with ext4, but I haven't really been able to follow them very well. My computer is a laptop, so it has a UPS (the battery) built in. Does anyone know some mount options that would improve performance. I'm not worried about data integrity since I have a battery.

im a bit confused. maybe one could shortly summarize which hardware would suit a given FS best as it seems solid state disks have some technical benefits that maybe the filesystem should be maybe aware of.
or maybe one could explain which test for which situation in usage stands for. (i.e. booting, handling large files, or any special situation a filesystem would be best suited)
maybe that would be worth an article...?
im quite impressed by ext3, and like someone before im even more wondering how the performance boost might have come, however surely its caused by not using the latest kernel. which means... to put it in terms of the help text for staging drivers in kernel config: could ext4 kick my dog when i wasnt paying attention, when i had one? (or: is it all that risky like it seems to me now?)

As you will see later this week, EXT4 is regressing even harder in 2.6.33.Michael Larabel

If the ext3 configuration used in the test was indeed not equivalent to the configuration of ext4 and btrfs then the results are _really_ interesting for btrfs. If its performance will not regress, it will beat the other filesystems hands on, based on the functionality. It doesnt look like ext4 will live long.

zlib compression allows you to write more across a link per second. Its actually a speed optimization. Now you are writing 120MB/s of compressed data across the link.
Assuming the cpu load is negligible in your case, zlib compression can help with bandwidth throttled workloads.
This is the driver behind compression under ZFS as well.
