Which filesystem you are using?

ha ha .. darkrose0510 that's really funny but scary too

ROFL! But aw! You owe me a new keyboard

I use JFS. The benefit of building my own distros is...

Oh my... Wonder how long will it take for me to reach that stage...

However, I saw some benchmarks for JFS and decided to give it a try; it's meant to be better for smaller files whereas XFS is better for big ones.

What exactly do you mean by small files and big files.. could you please explain... where in a system we find these...

BTW: you can use ext3 on a SSD, but you need to drop your commit time from the default 5 seconds to something less demanding to the drive, examples suggest 60 seconds.

What do you mean by 'commit time'?

What do you mean by 'commit time'?

How often the journal is updated to the disk. By default, it's kept low (5 seconds) so at any crash there's almost no data loss. Obviously, this has a negative effect on an SSD life, so the object becomes to balance life and effectiveness. You can use the commit= option in the fstab to change this default value. Setting a higher value improves performance and disk life, however, also increases the amount of work that could potentially be lost in a crash or power failure. For SSDs, I've seen a recommendation of 60 seconds (-o rw,commit=60), which will cut writes in 1/12th keeping close to a normal drive life span, while still maintaining an acceptable risk factor for the data on the disk.

List of ext3 options: Linux Kernel Documentation :: filesystems : ext3.txt

Edit:
There's also the option to place the journal on a different disk, say if you have one of those netbooks with several SD slots, you can in theory tie one up using an inexpensive SD card for your journal.

Can you share how you built your own distro?

Yes I used LFS to build a bootable base from which to build upon. I've built my own distro so many times that the book has become more like a rough guide. For instance I was using gcc4, glibc 2.4, and the sanitised kernel headers long before they were entered in to the book; basically I went in blind and fixed whatever issues came up - for which there were quite a few. I'm actually working on a new distro at the moment, I finished compiling X the other day and that's turned out well.

I'm talking about the size of the files. In a typical distribution you will have lots of small files - such as configs, libraries, binaries, logs, etc - in contrast to an FTP that might contain lots of 10M+ tarballs. XFS is meant to be great for large files - which makes it good for use on, i.e., FTPs - and JFS is great for small files - i.e., a system with a typical distribution or a server.

I use ext3. I'll wait until ext4 has been around a little while before I try it.

I keep my music files on a FAT32 partition. And very briefly, my iPod was formatted with hfs+. **shudder**

Have always used ReiserFS and Ext3 mostly but have been using XFS a lot recently.
