I have just installed ubuntu 12.10 (32-bit version) on my old Toshiba Satellite (496.3 MiB, Intel Pentium 4 CPU 2.40GHz processor, NV17 graphics card, 58.5 GB HD). Although this is an older system, it ran Windows XP smoothly and fairly quickly especially compared to ubuntu. I had installed Knoppix 6.5 just prior to ubuntu. Knoppix installed easily without any issues and ran at a good pace. After installing ubuntu, the speed of opening applications or folders takes a few minutes to complete. Is there anything I can do to increase the speed of this OS? Although I'm new to the linux world, I'm testing out these OSs to see which I would like to install on a netbook for future international travel so any assistance anyone can provide would be very helpful. Thanks!
