Approved: Fedora 33 Desktop Variants Defaulting To Btrfs File-System

[sireangelus]

Actually, I was expecting Steam to pop up. Steam distribution system is a nightmare. They do a fsync after every written file! So, if apt is bad, Steam is one of the worst. Personally, I have a separate ext4 formatted disk for my Steam installation, since it won't fit my main drives anyway.

Regarding thumbnail generation: which software? I don't see how writing new files could cause IO stalls like what you're implying. I'm using btrfs in a lot of systems (most of them in a desktop/workstation role) with photos and videos in the thousands for any particular user: never seen something like that. But I don't use ubuntu (their kernel backporting and patching is garbage), and I don't use gnome.



That's a bold statement. Bad applications exists (two examples above) and btrfs does indeed suffer more in situations where an excessive number of fsync calls are being issued, but to call it bad for any kind of workloads isn't accurate. If you believe phoronix's numbers, you will see this. If you don't, btrfs developers are working on sane benchmarks; synthetics are mostly useless, in most cases.

dolphin. I mean i make a pretty generic usage of my workstation- from gaming to virtualization to office work to media work- and i can tell that it's just so much slower than when i install ext4. You can feel it. It's actually measurable.

what are you talking about? are you off your meds?

Really son? How will you convert for example ext4 to btrfs system partition table while your system is running?

Do you know which one year we have currently?

Do you know any more recent benchmark?

Can you show or describe one example of the workload under which Solaris 11.4 is slower than Linux?

No, the EULA forbids me from doing so without Oracle's consent
It cuts both ways lol

I mean 2012, which is the same major release it also is at now, btw, while Linux has increased on any metric.

How old are you? (ruffly +/-5 years)

Enough to be in bed with your mom, and make you call me daddy.

[starshipeleven]

Sorry how did you get that?

Sorry don't mind me, I'm just quoting your very own posts:

Are you aware of very simple facts that most of the read workloads are random and only very small number of those workloads are sequential?
What happens when distribution of the blocks is random and you are reading randomly? Mostly nothing .. you have ~the same level of randomness on reads.

Nope.

It also reduces amount of fragmentation as there is less stuff inside the block so it does not need to read as much useless data just because it is in the same blocks as the data it is looking for

It is not at all because none of the ZFS fanbois cares about fragmentation

fixed

Windows has nothing to do with ZFS.

I use this on OpenSUSE:

You will gain small amounts of performance if you change to "compress-force=zstd". You may also want to benchmark and see what compression level is good for you: https://wiki.tnonline.net/w/Btrfs/Zstd (benchmark tool)

EDIT: Oh and I so do not like the '@' naming scheme so many are using!

[kloczek]

It sure was in the last benchmarks before that went up.

Lies, people has been laid off and information about the situation also hit the streets
