read again, the only reason was the easy migration from ext2... they even skipped ext3 - which should tell you something.

If the test is made with a single thread then it is almost a tie. With the default 4 threads deadline wins. The write performance is better but read performance is the about the same |

Not the only reason, just the main reason for picking EXT4 over XFS.

and if you read your own link: XFS was faster. hmmm... faster.. better tested. Sure, when you have the hardware available google has, ext4's fucking brokeness might not be a problem...

Sorry, but some anecdotal evidence is not convincing that EXT4 is broken.

thx a lot!
guess that majority desktop users depend more on read performance to achieve interactivity, but I'll stay with deadline for the time being.

I have 10TB+ on ext4 at work. Not a single problem at all. However at work I do not upgrade the kernel every month..
