confused by flash performance Slackware vs Salix
I'm confused by this. I installed SalixOS on my laptop just to play with when I'm bored. My laptop is nothing special, it's a couple of years old
has a pentium dual core t2390 at 1.86Ghz and 3 GB ddr2 RAM with Intel video. I then have a beast i7 920 clocked to 3331Mhz 6GB RAM, and an NVIDIA GT220. Full screen youtube at 720p is fine unless I move the mouse, then the whole picture freezes. Persistant mouse movement will freeze the screen for a few minutes. This machine runs both slack64 current and slack13 32 bits. The slack box does much better with 32 bit flash than 64, but it still doesn't do nearly as well as the laptop. With Salix and Slack being so close to each other supposedly I can't figure out why the hardware seems to be irrelevant. The only thing I can think of would be the video codecs installed by Salix, whereas I built a bunch of codecs myself for Slack. Any ideas? |
You're not comparing the performance between slackware and Salix, you are
comparing the difference between two different graphic hardware installations. If you want to compare the difference between slackware and salix, you need to install OS's on the very same hardware and run tests to compare the differences. There a few attributes which may explain the behaviour of your Nvidia installation. Like what device driver are you using to drive the card, what version is it. Are you on the latest Xorg version. Does Xorg have the raw display performance options compiled in ? Some of the suggestions for improving the displaying video at a real time rate can be found the the mplayer documentation. |
I was actually comparing 32 bit flash vs 64 bit flash. After triple boot trials (slack 64/32 bit salix 32 bit) I determined that flash video is, in fact, identical on slack and salix using 32 bit.

Thanks for investigating this. 64-bit Flash's performance on Linux is awful.
Have you tried running 32bit Flash in nspluginwrapper? (I did years ago, but the performance was not good). Or have considered switching to a 32-bit Firefox, which would be possible in a multi-lib setup? |

I have higher hopes for the 10.1 for 64 but I'm an optimist. |
Can you describe what you mean by 'flash performance on 64-bit is awful' ?
I run 64-bit on opensuse and the flash apps display video fine. Are you talking about sluggish display ? Start/stop of video ? |
I've had no problems with flash on Slack64.

For me the problem is in hi-res full screen, like youtube 720p at fullscreen........it plays fine, doesn't kill my system, but if I move the mouse the video hangs, and if I move it for a few seconds the video locks and I can't even ESC out of fullscreen until it decides to sometimes 10 seconds. I get nothing like that on 32 bit flash. And you can forget about hulu.com. Personally my browsers never crash with flash, except for the development 3.6.4 of FF that I'm running on an old Ubuntu install.

EDIT: And Damgar, I just watched this movie full-screen at 720p. I even moved the mouse several times. The audio stayed in sync for the entire movie. The only problem was a bit of screen tearing. http://www.youtube.com/watch?v=v-Gfkb04DNI |

Code:
bash-4.1# /usr/lib/firefox-3.5.2/firefox |
Try running /etc/rc.d/rc.M again.
I don't have libgconf installed. |
Reinstalling my Nvidia driver per the instructions and rebooting solved the problem. I am now able to watch full screen youtube in 720 and move the mouse all I want. Hulu.com works as well. Thank God for AlienBOB! It seems like a long way to go, but that's the beauty of opensource .... there's almost always a way! Thanks for taking an interest. :)

Ahh, that explains it. I **never** run you-tube at full screen.
I have a very very large screen. I bet the upscaling of the video to my full screen would kill the performance. |
