[SOLVED] glxgears for 2d & 3d benchmarking?

keratos · 2009-04-30 12:47:35

Read on these forums that glxgears is not a comprehensive test that adequately excercises the graphics subsystem.

However at the same time I note a significant number of members quoting glxperformance performance increases/decreases under KMS,X,Intel driver,UXA/EXA/XAA.

Can someone with authority explain (without using webpage links) whether glxinfo is a suitable benchmark, or not. If not, then what is?

Thanks.

LOL, i don't seem to fit in the "authority" category , but it's something like this:

GLXgears is not a benchmark. benchmarks should rely on multiple tests of individual features of gpu, and then put the numbers togheter in order to make a final parameter of general performance.

GLXgears is, however, widely used as a parameter for video performance due to a long time tradition of linux 3d measuring, since for a long time there wasn't almost any other way of doing this on xorg.

So, in newbie language, GLXgears is not a benchmark but it's a performance parameter.

In my mind, a benchmark = a set of performance parameters. Thus glxgears is one of many parameter values required to benchmark a system.

Can you recommend a benchmark app for a modern arch install please?

The reason I seek such an app is because I am evaluating the performance of intel X driver and kernel KMS with certain X server settings and acceleration methods. Strangely, glxgears reports significantly lower values with more "modern" configurations. I am presuming that this is a parameter value drop but overall a benchmarked system would repoert higher performance. This presumption needs to be asserted as true or false.

Thanks

Install phoronix-test-suite and use its X11 related tests, e.g. qgears2, render-bench and x11perf.

keratos · 2009-04-30 20:17:59

installed it from arch repos (pacman) however

when I run phoronix-test-suite, nothing happens, just returns immediately to the command prompt.

tried installing source from phoronix website. this was slightly better as now the '.. list-suites' reports all the tests correctly. However, whatever test I run it wants to download lots of tests but each time I get the error:

Downloading File: trislam.tar.gz

No downloading application available.
The MD5 check-sum of the downloaded file is incorrect.

Download of Needed Test Dependencies Failed! Exiting.


Installation of trislam test failed.

trislam.tar.gz is one of the files that fails...there are many more!

ideas?

mutlu_inek · 2009-04-30 20:59:07

The one from the arch repos works more or less well. I just double-checked and the trislam test installs without problems.

phoronix-test-suite install x-testing

should get you all you need. It will probably ask for qt4, just give a false password, since qt (which I presume you have installed) provides for it, only the test suite isn't aware. I hope this will be patched some time, but isn't really a problem.

Why glxgears is slower with Kernel Modesetting (and why it doesn't matter)
or: "glxgears is not a 3d benchmark"

As for useful benchmarking, there is also mesa-demos and FBENCH.

Hmm... I don't get those errors. But I found this thread, maybe it helps: http://bbs.archlinux.org/viewtopic.php?pid=515816

keratos · 2009-05-01 09:39:26

Nope. Cannot get it working although I have to say I am not a PHP nor coding expert - nor do I wish to be - I just want something that works , Simple!

I recall the Arch mantra was "Keep it simple" !!!

Can anyone pleae point me to something in arch that we can use as a working metrics/benchmark tool.

SuSE Ubuntu Fedora even Gentoo all have working packages. I've used them !

not sure how that post is supposed to offer a solution!

? how about elaboarting and providing some form of link or instruction?

what is not clear is why a package that is available from the repos, needs to be tweaked. how bizzare

No, it is not bizarre. This isn't Ubuntu, nor Debian. KISS does not mean that it works magically. http://wiki.archlinux.org/index.php/The_Arch_Way

I checked quickly, the .install file of the phoronix-test-suite package looks like this:

post_install() {
  echo ">>>"
  echo ">>> To complete the installation you should edit /etc/php/php.ini."
  echo ">>> Add / to the open_basedir list."
  echo ">>>"
  echo ">>> EXAMPLE:"
  echo ">>> open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/"
  echo ">>>"
  echo ">>> To enable the GUI make sure you install php-gtk from aur"
}

I.e. instructions were given at install time; this is fairly common.

keratos · 2009-05-03 09:47:48

One has used *nix since 1979 and confess to being a novice linux admin since good olde RHv1 ! in my view , this IS bizzare - a package management system and repository that requires user intervention to configure the system post-install. Not seen that before! Nevertheless, I shall try your kind suggestion and report back.

EDIT:
------
apologies. dumb me. this is the php init file and for security reasons the root fs is not enabled by default.

you are of course, correct.

sorry

I get your point, though. If it required user intervention post-install for not security related things, it would certainly be a bug.

agreed. closing thread now. thanks for the assistance.
