  Hi, I run ubuntu studio 8.04 on an amd64 and the first time I freshly installed it on my computer it behaved like yours. Apps ran extremely slow.. only opening a terminal could take 1 minute.
  Then, I reinstalled the system and since that second installation everything seems to work normally.
  The only thing that I did differently between first and second fresh installs was that during the first installation (the wrong one) my computer was connected to the internet and during the second it didn't.
  Hope that it helps you.

This sounds like possibly a low memory situation, where your RAM is not enough and so the OS goes to the SWAP file. It could be that the swap file is too small and by increasing the size of your swap partition or RAM will help. If you can add RAM to your computer, try to fill it to capacity, it never hurts to have lots of RAM. It could also be the processor speed, if your computer has less than a 1GHz processor, it can slow things down. Faster is always better. I have some older PC's that run Ubuntu, but they are much slower than my newer ones. Especially with RAM and processor intensive operations like burning CD/DVD. Just a guess though, if you have modern hardware, it could be something else.

Hmm, I've got a dual core 2.4 AMD64 CPU, with one gig of RAM. I'm not doing any operation I haven't done under Windows XP, in which case everything worked just fine. One thing I haven't mentioned is that I run the 64-bit version of Studio. Anyway, before I upgraded from 7.10 to 8.04, everything ran more or less fine. But the fact that everything else starts getting affected by the burn process was there before. I believe it has worsened. I've tried deleting the dotfiles for Brasero, but it doesn't change anything.

I will watch RAM usage next time just in case.
Nope, CPU and RAM usage stay very low the whole time, just tried creating an ISO with mkisofs. But every other app just gets very laggy.
