When amarok plays it use about 6-8% CPU-time with disabled analyzer, for example xmms uses 1-2%. Is it possible to fix this issue ?

I use amarok-1.0-beta3 on my kde-3.2.2

First of all, what engine are you using? If you mean aRts:

aRts is much more complex than XMMS' sound system, so it inherently needs more CPU time. We can't do anything about it.

I recommend checking out the GStreamer engine, since GST seems a bit faster than aRts for many tasks.

Gstreamer engine doesn`t help me

8% sounds like you didnt install kde-multimedia's mp3 codecs.
doing that reduces my load to 2% (xmms-like).

Hm... I`ve got full kde installed on my gentoo box and kdemultimedia with flags --with-alsa --with-arts-alsa --with-vorbis=/usr --with-lame=/usr. Here results of serarch *mp3* in kde dir:

[snip]
/usr/kde/3.2/lib/kde3/kfile_mp3.la
/usr/kde/3.2/lib/kde3/kfile_mp3.so
/usr/kde/3.2/lib/kde3/libkrecexport_mp3.la
/usr/kde/3.2/lib/kde3/libkrecexport_mp3.so
[snip]

P.S.: Sorry for my poor english. I`m russian

look for those files:
/usr/lib/libarts_mpeglib-0.3.0.so.0
/usr/lib/libarts_mpeglib-0.3.0.so.0.0.3
/usr/lib/libarts_mpeglib.la
/usr/lib/libarts_mpeglib.so

All of these files exist om my system

I've these libraries into /opt/kde/lib .
Can this modify amarok performance ?
I've the same problem : more than 10% of cpu usage !!
I've installed gstreamer from .tgz (I'm usign slackware) and the package amarok 1.0beta4.
When try to activate gstreamer amarok goes in crash when push the play button. Why ?
Another thing : alsa is update to the version 1.2.2.

did you run gst-register before starting amarok?

gst-register needs to be called once, after gstreamer installation, so that the engine can detect the plugins. (see amarok faq / gstreamer readme)

Thanks, that fixed it for me.

Hi there,

I\'m using this thread so nobody points me to the search forum button

I installed amarok today and so far I like it quite a lot. But according to the topic I was wondering about performance too. When playing an mp3-stream I took some rough figures for cpu-usage:
xmms 9%
amarok-xine: 13%
amarok-arts: 18%
amarok-gstreamer: 20%

All Windows closed so no Analyser-painting involved. This is a P3-650, I am using amarok 1.1.1, gstreamer 0.86, alsa 1.07 kde 3.3.1 kernel 2.6.9, well...

So besides checking for those libraries, is there anything I can do about it? And regarding the recent discussion proposing gstreamer replacing arts is there anything you could/would do about it ?

TIA
