Hello all,

I'm building a box, Dell precision 470...dual Xeon 2.8Ghz cpus, 1x 1TB sata drive.

I'm wanting to play with this box...running a mythtv backend on it...and also going to mess around with some VM stuff using maybe qemu or virtualbox

I'm setting up /boot with ext3

I've always used reiserfs in the past, but, with it not being worked on much anymore...etc...I was thinking of trying something like XFS or JFS.

Would one of these be better to use for my / dir?
What about the other partitons I'm going to do under LVM? I'm doing partitons for holding the myth files which are pretty large...I'll be doing lvm for /opt /usr, /home, /tmp too.

Would it be best to mix and match for the /media partions vs the ones listed above?

Can someone give me some pluses and negatives on XFS/JFS?

Thank you,

cayenne

At my current employer I did a benchmark of file systems.
They were running reiserfs on their old machines and the performance was good, I was however hesitant to install new machines with reiserfs for various reasons.
I ran tests using ext3, reiserfs, JFS, and XFS. The test tested small -> large data chunk sizes and also small -> large files and all combinations.
In short I came to the following conclusions after my test.

ext3 performs very evenly in all combinations but the performance compared to XFS and reiserfs was not so good.
reiserfs was the best performer accept for when using small file sizes.
XFS has better performance when using small files and an almost equal performance to reiserfs when using medium -> large files in combination with medium high -> large data chunk sizes.
JFS is not in the same league as reiserfs and XFS when it comes to performance.

We ended up choosing XFS and in tests using our applications the performance of XFS and reiserfs was almost identical.

reiserfs.
I tested reiserfs, ext3 and xfs, and reiser id the best.
you can read something in phoronix web site, ext4 promisses, but is not as stable as reiser or ext3 and have a lot of data lost during power fail
