Hi, We recently switched from g++ 2.95.3 to g++ 3.4.2. This has resulted in increasing the total compile time of the project by about 2-3 times. Infact if I just compile one file at time 3.4.2 takes about 5-6 times more than 2.95.3. I see that many people have reported the same issue. Is there any improvement that could be done to improve the compile time in g++ 3.4.2? Thanks, Sheik.
That's why I continue to use 2.95.3, and probably will continue to use it for the remainder of my career, whenever I am free to make that choice.
That kind of slowdown is HUGE.I wonder if I can ask, without offending any of the hard-working developers of gcc: Has anyone made a study of just why gcc got so slow after 2.95.3, and whether any profiling has been done to improve this?
