poor performance
Hi,
I am using Redhat 9.0 and j2sdk1.4.5. When I run my java application using swing and jmf which involves display of pictures/images or video clips as per an interactive user request, I find that it becomes very slow when I run other applications in parallel. What could be the reason? Thanks in advance |
What are the specs of your computer? Run top, vmstat, etc.. to get a display of what's eating up your computer. Also, kill all unneeded processes.

When i am playing video using java media framework and run an application that only prints a string in endless loop the video bcoms drastically slow... if the video is the only application running its ok... if i use any default player of linux and run the printing application also the video plays fine... what could be the reason?
my m/c has 128mb ram and is pentium III 700Mhz |
128mb of RAM is a little on the low side. Double it - at least - and you'll see the difference.

I would agree with Lim45 on this one. Running anything on video is very memory intensive. Monitor your swap usage the minute you run on video and then run another application.

Even with 256mb memory, I find that the video bcomes a little slow when other applications are running

I gotta agree more memory is needed. If your m/b will handle it go with 512 or 768 mb for playing movies and running other apps or try a lighter wm.

lighter wm means?

Lighter Window Manager. If you're using the default Gnome or KDE which come with RH9, they will in themselves be using a fair chunk of your valuable system resources. There are plenty of others you can try which will make better use of your available RAM - I don't know what comes with RH9, never having used it, but XFCE or IceWM might be good choices. Others might suggest Fluxbox or Blackbox, but they might be something of a culture shock after Gnome/KDE....
I use XFCE on occasion, and it's noticably snappier than KDE, even with 512mb of RAM. |
