Minimum memory for a Fedora installation with a graphical User Interface is 192mB RAM. Only solution is to add memory to your machine. I'd advise at least 512mB. An AMD K6_2 isn't really fast enough for FC2 either. Downgrade to RH9. Or get a faster basic system. RH9 will cope with the smaller memory , just about. Distributions suitable for smaller memory machines do exist, but support can be patchy. The freshly released mainstream distros all need large amounts of RAM, especially if you install all the GUI stuff. > Any hints or sites where I could find the basics on improving performance? > Should I try another Linux? No, try a different system. FC is fine, if you give it the machine it deserves. Trouble is, people are USED to Windows running slow ( because the programmers have learnt to use tricks to make it appear faster visually than it really is ... MicroSoft's dictats on Good GUI Programming have seen to this ), but expect Linux for some reason to be faster. Windows programs normally cheat. They load the visual window first, then complete loading of the dll's. They move the code for the GUI into the executable, then load whatever libraries the program needs. That way the user gets a quick sight of the program, and thinks it is running. Meantime, its still busy churning away at the disk. Linux does run faster, but Linux programmers haven't had to resort to this level of cheating so far. So comparing the times taken for similar apps on windows and linux - on identical systems - just by watching the screen isn't a valid comparison. Windows looks quite good even on computers with smaller amounts of memory It relies heavily on swapping, whereas Linux, which because of its filing system has a slightly higher disk access penalty, tries to do more in RAM. (At least thats the way it appears to a me, as a self-taught programmer of 20 years exp. Mebbe the rationale is totally wrong. Quote it at your own risk.) When Win 95 came out, a generation of computer users had to upgrade their hardware. Ditto the next release etc etc. As we the users demand more and more from Linux, it is inevitable that the demands on the hardware are increasing. Linux is a totally different way of thinking. But at least we CAN use smaller sytems with the same OS, albeit by shedding applications. Even if you shed all your applications on WinXP, you still wouldn't get it onto a 286. At least all the 'bloat' in a modern linux distro is in the applications in each distro, rather than programmed into the kernel. You could never install WinXP in an early generation 286. Shave all the extras off a Linux Kernel, and it'll run, just. > > TKS, A > > > --------------------------------- > Yahoo! Acesso Grátis - Internet rápida e grátis.
