Ext3 users - Jan 2004 - ext3 performance

Hi all,

I have a question about ext3 performances...

Is there a difference in performances between a filesystem directly 
created with mkfs.ext3 (with default parameters) and a "tune2fs -j" 
converted filesystem from ext2 to ext3 (with default parameters).

It's in a case of a filesystem with big IO usage.

Basically, no.  You get the same journal size, and etc.

With tune2fs -j there is a possibility of getting a fragmented journal file
if there isn't enough contingous space available on your converted
filesystem.

You can check it with debugfs though...
