Phoronix: FreeBSD 8.0 vs. Ubuntu 9.10 Benchmarks

Canonical will be releasing Ubuntu 9.10 at the end of next month while the final release of FreeBSD 8.0 is also expected within the next few weeks. With these two popular free software operating systems both having major updates coming out at around the same time, we decided it warranted some early benchmarking as we see how the FreeBSD 8.0 and Ubuntu 9.10 performance compares. For looking more at the FreeBSD performance we also have included test results from FreeBSD 7.2, the current stable release. In this article are mostly the server and workstation oriented benchmarks with the testing being carried out on a dual AMD Opteron quad-core workstation.

Statistical analysis

Some statistical analysis would be nice to have in the future. Here's a short description of a simple tool with which to do it.

[Kano]

I did not look at the code, but maybe it executes the external md5sum tool.

Well, I'm about to give up.

I've just spend 8 hours trying to get Phoronix running in FreeBSD.

Running the install-sh program puts everything in /usr/bin and /usr/share/phoro* but doesn't make a pts / pts-core directory, so I need to cp those from the install directory to /usr/share/phor*/ before the program will think it is installed.

Once that is past, if I try to run an install, it says the checksum fails, but I can download the file and the checksum matches.

The only way I think I could manage to do these tests is to do them by hand and not use Phoronix-test-suite. Which I really don't have the time to do all these tests by hand. I've already spent close to 16 hours installing/prepping this.

Errors that I can't debug:
test# tar -xf phoronix-test-suite-2.0.0.tar
test# cd phoronix-test-suite
test# ./install-sh

Why 250 Hz? To be more server oriented? If yes then he should enable and the "no forced preemption" option in the proccesor type and features and also to choose the correct type of processor.

Yep, it's noticeable in the test I gave a link. :>

http://unix.derkeiler.com/Mailing-Li.../msg00073.html - it's buried there somewhere

[Apopas]

I do not have enough knowledge to help you. For Ubuntu I would just turn off debugging, chose 250Hz option, disable some services, because sometimes they can 'eat' up to 100% cpu (afaik some package management related)...

No one here willing/able to help me? If not, I'll have to abandon running a new series of tests.

I've got the hardware and can run the test on the bare metal, I've got the time to do the OS installs and the optimizations I'm able to do (FreeBSD), but I don't have the time to learn how to run the phoronix-test-suite.

While I am responsible for a number of Linux systems (mostly RHEL and Gentoo), I wouldn't consider myself an expert on optimizing Linux.

If no one has the time or desire to help, that is fine. I understand. If you do have it, please help with these:
1) Install and Optimize Ubuntu on the hardware.
2) Run the Phoronix Test Suite with the same options as the original test.

I don't know how Michael Larabel ran it originally (what options.) I also can't get it to run on FreeBSD. It installs (with install-sh) but then errors out immediately with this:

To run the Phoronix Test Suite locally you must first change directories to phoronix-test-suite/
or install the program using the install-sh script. For support visit: http://www.phoronix-test-suite.com/

I'm running it from the directory and /usr/bin/ is where the suite binary is located.

If I can't get help soon, I'll need to put the new box into production middle of next week. If in production, it will have 8 production VM's on it which would make it worthless for any meaningful test.

For Ubuntu I would just turn off debugging, chose 250Hz option, disable some services, because sometimes they can 'eat' up to 100% cpu (afaik some package management related) and if you plan to optimize FreeBSD as much as possible I would also use writeback mode and Ext4 file system in Ubuntu. The best option would be probably to ask at lkml about how to optimize it

turning on writeback:

http://bbs.archlinux.org/viewtopic.php?pid=622697

I did not run PTS on FreeBSD, but on some Linux distros if PTS is already installed (if not I just cd to its directory and do ./phoronix-test-suite [...]):

phoronix-test-suite list-tests - to show available tests,
phoronix-test-suite install [test_name]
phoronix-test-suite benchmark [test_name] no special options are required afaik.

To make it running in Arch I had to change some option in php like described in this thread:

http://bbs.archlinux.org/viewtopic.php?id=46504


However, it seems there's nothing wrong with the results:

Without context, you can't make that decision. There may be any number of scenarios that would dictate that sort of configuration. (For example, 3 server application licenses that require 3 OSes, but will be within the capacity of a single system). In that case you want to have the app in the right spot and/or VM. You then choose benchmarks that represent your application.

The intent of the benchmarking should be made clear, but without it you can't declare a benchmark invalid.

With the intent you can call into question two items
- the analysis and consequent construction of the testing.
- the analysis and conclusions of the testing.

I do agree with you, but I thought the context is rather clear, this being a thread for discussions about the results of the Phoronix's benchmarks.
Besides, if you want to compare the performance of 2 or more OSes, my guess is that you'd want to have the least possible interferences with the running OS.

I was according to this:

http://people.freebsd.org/~kris/scaling/os-mysql.png

If 2.6.22 was tested here and there (also in benchmark I posted) I wonder what they base on saying some scaling problems were fixed in 2.6.22?

Ok, now I know:

http://jeffr-tech.livejournal.com/5705.html

There's gnu's malloc used and that's why 2.6.21* drops down.

And with Google's malloc:

http://ozlabs.org/~anton/linux/sysbench/

It could be like this. However, there's/was known problem with GNU's malloc library and I wonder what library was used (it seems it was used). There's also 2.6.22 test which I'm according to.

That's why I'd really like to see a new benchmark. Unfortunately I simply don't have the HW necessary for it at my disposal to do it myself.
