Why is CB so slow only in Linux?

<< < (2/3) > >>

Jenna:
If the gui is slow it can be a graphics driver problem.

By the way I am on debian unstable/experimental 64-bit, with xfce, ati graphics-card and radeonhd-driver.

In my own testing, I've noticed that using xfce instead of gnome/kde *seems* to help. worth investigating further

I used it on lxde and gnome and have C::B installed on another computer under kde (intel graphics) and it is not reasonable slower.
All debian 64-bit.

On my virtual systems, there is also no problem with C::B's performance, except for compiling what takes longer, due to less memory.

If compiling takes half a day you have a problem on your system that has nothing to do with C::B.

Compiling with automake-system needs more time than compiling from inside C::B, but that's because of the optimization settings.

Problem is not compiling. I think compiling inside C::B in Win and Linux are about same speed. Automake systems I do from command line.

Aha! So that will be it! Because on my OpenGL applications I noticed, that in Linux they are much more slower. On old Ubuntu it was about 25%, now its about 50%, in Debian it was even about 75%. So if I want fast C::B in Linux, I need new laptop, huh? I have Intel integrated graphic card.

Anyway, thanks for replies :).

Jenna:
I have an integrated intel card on my wife's office system (don't know the type at the moment), also debian unstable 64-bit, but with kde4 and C::B and OPenGL-software run fine there.
