Re: [orca-list] Misteries of low performance of Orca and distros

[Alex Midence <alex midence gmail com>]

I bet you have a driver that isn't playing nice with Linux.  Every one of
the distributions you named should work very well and should give you much
larger performance increases than windows.  I would open a terminal and do
an apt-cache search for firmware-nonfree and install the metapackage.  It
might have the driver that is messing with you on it.  Have you looked in
system monitor to determine what is going on with your machine while running
linux?  An i5 with 4gb of Ram should be zipping along real good for you in
Linux not slowing down.  

Hope you get it resolved,
Alex M

Subject: [orca-list] Misteries of low performance of Orca and distros

Hi listers,
I am using Orca 3.2.0 and Ubuntu 10.10, but I really need to upgrade it.
However, I am facing severe issues about performance. I have a Entel I5
processor with 4 gigabytes of RAM. It's not a bad machine, but, under Linux
environment, the performance has never been good.
Under Ubuntu 10.10 and orca 3.2.0, the performance is acceptable, but when
Windows is run in the same machine, the difference is immeasurably big.
Windows is much faster.
The problem seems to be more severe in my attempts to upgrade. let me show
you my failed instalations:
1. Sonar (ubuntu 12.04) - After the instalation, the performance is very bad
compared to Windows and the current distro (ubuntu 10.10). I don't know if I
would be pacient with so weak performance, but the true reason I uninstalled
it is that there is a problem with portuguese translation package.
2. Vinux (Ubuntu 12.04) - For three times, I tried to install it. 
Firstly, the installer failed with an unknow error 5. Secondly, it was
reported that the media was probably corrupted. Thirdly, error 5 was shown
again. I used  three different medias, so it's not easy to suppose media
corruption. The DVD unit seems to be working appropriately becose I can run
and install Ubuntu 10.10 without problems. But the important for the purpose
of this message is that I could not install Vinux, but the installer works
efficiently in terms of performance.
3. Ubuntu 13.04 - The slowness was so critical during the instalation that
Orca answered after 10 or 15 seconds after a command. I don't refer to the
natural time consumption for the DVD scanning. No, it seems to be related to
the RAM. I can't understand what is wrong.
Is ubuntu a very slow system? No. I can't listen to people complaining about
this.
Is my computer broken? No. Windows is running with a very, very good
performance.
Could I have a hot processor? It's always a possibility, but when I place
the hand on the refrigeration output, I can feel the wind. I can
additionally regard that hardware problems certainly would affect also
Windows and, as I have mentioned, windows is running so faster.
The fact is that orca, under Sonar (ubuntu 12.04), did not answer timely.
And ubuntu 13.04, during the instalation, the issue was meaningly worst.
I do really want to use newer versions of Orca. From Saturday to Sunday, I
tried to install Vinux and Ubuntu 13.04 for six five times and six
reinstalations of Ubuntu 10.10 was needed, totalizing 11 instalations. 
Yes, I am really dedicated to complete the task.
However, a mistery keeps unknown: why can I get good performances if my
machine is able to deal with it?
If the reason keeps unknow, the solution is to try something different. 
I can try to install Vinux, since the problem was not related to performance
up to now.
I can insist with Ubuntu 13.04, expecting that after instalation its
behavior will be much faster.
But I can also try to use another distro, perhaps, a non Debian distro. 
So I ask:
1. Do you have any idea what I can do to discover what badly affect the
performance of my machine when I use Ubuntu?
2. Which distros I can install without any help of a sighted people?
I sent this message to the orca list becose my purpose is find any
alternative that allows orca to work efficiently. Therefore, it's not aa
specific doubt about one distro. Actually, it's important for me to choose a
distro accessible during the instalation and with newer and faster orca
versions.
Regards,
Luciano
