I am looking for some information on user's experience with XFS versus EXT3. I have googled this question and looked through prior threads, but the information was inconclusive to me. Here's the situation, I record video with MythTV and the typical size is between 4.2 GB and 7.5 GB for each file. The system is a little old, but still pretty powerful.

System Spec's:
Basically I want to know if anyone thinks that for typical files that will be somewhere between 4 GB and 8 GB, do you think that EXT3 or XFS will provide the system with better performance? I have been using it for a few days now with no problems, but I have been wondering if XFS would just be handle better by the system.

On my MythTV box, I use XFS on top of LVM2 for the recordings directory (with all those big files) and EXT3 (also on LVM) for most everything else. I did not do personal performance testing, and just picked XFS based on testing reported by others. It is reportedly good with large files. Works fine for me, but I did not do an a-b performance comparison with any other filesystem type.
