Hello again, Thanks a lot for all the help, well ... I now use reiser4 as root-partition :-)
Everything works ok and I haven't seen any crashes or compatibility problems, simply wonderful :-). If something bad happens I'll let you know ;) However performance is so-and-so, the system was faster with ext3, although I compiled the kernel with "-O3 -march=pentium4 -mtune=pentium4 -mno-sse -mno-sse3". Booting the system into KDE takes about twice the time, although I have to admit I was using another harddrive - I now use a 60GB/4200RPM instead an 40GB/4200RPM which both show quite the same hdparm-results, I use the lzo1 plugin (default ccreg40). Are there some settings (or ext3 optimizations) in FC6, or could it be that some of my kernel-settings slow things down for FC6 (the same compiled kernel-binary was already used for ext3). The reiser4-partition is mounted with "noatime". These are some features I could imagine causing problems: * Inotify * Adaptive file readahead + hit feedback + fine grained readahead aging * Timer with 1kHz * Readahead-script of the distribution Thanks a lot, lg Clemens
