Hi Istvan, Thanks for your reply. I did some searches on google and found one thread where the user reported 4.1 being faster than 4.0 and also a little bit faster than 3.4. One thing that has been mentioned all around and something I noticed too is that 4.1 is slower to compile things as it seems to do much more passes over the code when compiling. As 4.1 is the default now on Fedora Core 5, it'll be what I use, so was just curious about results.
