ext3 or ext4 for squeeze

[adrifoxbg]

I've heard that ext4 has better performance, but that it will also eat my hard drive. Has this problem been fixed? What would be a safer bet on a squeeze box? Is there even anything to worry about?

I have the same problem. Debian 6.0.7 is fast, but Debian 7 slow. If you have a website, and running MySQL, here's the problem. The new version of MySQL is very cumbersome. Here's an example my site installed on Debian 6.0.7 for 49 seconds, on Debian 7 website installed for 11 minutes.
There is one more thing that bothers me, even when you adjust the mouse is a fast or slow, hard drive again and thinking too noisy

For ext4 disable barriers for better write and fsync() performance at the cost of some reliability. To test this, try installing Debian packages with ext4 and time it. Then disable barriers with mount option nobarrier (and reboot or remount), drop cache, and try it again, note the speed improvements.

Is it worth it? Up to you. I would say for anything needing good performance in that area just use ext3. I partition my systems using raid1, with lvm. And the lvm uses different file systems for different mount points. I use xfs for anything not otherwise specified, and ext3 for /var and /boot.
