Performance ?
by MandrakeUser on Thursday 08/Jul/2004, @09:37

Hi

Does anyone know how is Qt4 going to do in terms of speed ? I think I read some time ago that one of the focuses for Qt4 was to speed up the libraries, besides adding functionality, but I don't see any reference to this in the Public Release info ...

Lots of tunning. QString, moc etc. expecting a good bump in startup and speed.

Thanks Ben, looking forward to it ! This, together with a standard objprelink for Linux, plus KDE-libs optimizations, will overall get an even snappier KDE !!!!!!

Being slightly pedantic: objprelink has nothing to do with Linux, it addresses an issue with gcc's C++ implementation. Any system that uses gcc will be subject to the same problem. If you use a different C++ complier for Linux (does anybody?), you don't have the problem. And yes, gcc has addressed the problem directly, so it's an issue that will fade away.

You are correct in all of this.

That's what I love about Linux. My old piece of crap computer is getting faster all the time.. From kernel 2.4 to 2.6, from KDE 3.1 to 3.2, etc.

In a few years I'll have to downgrade :D

An old P350 with 128mgs of Ram feels snappier with KDE3.3 than with KDE 3.1.
Does the upgrade from 2.4 Kernel to 2.6 improves performance, too? If so, I'll certainly upgrade the kernel on this slackware box...

The new kernel is a tad bit snappier on interactive loads, but these improvements has been available for 2.4 as patches for some time. So you may already have them if you are running a distro kernel.

SuSE 8.2 with KDE 3.1 and Linux 2.4.20 felt snappier to me then
SUSE 9.1 with KDE 3.2 and Linux 2.6.4, so I downgraded.

(on a mobile P2 400MHz with 160MB RAM)

Well, this is SuSE specific, cause SuSE is a well overloaded Distribution
which (my opinion) is not at all made to achieve the maximum performance!

Slackware doesn't include any of these patches in its default kernels....

To answer the question one layer up: Yes, 2.6 speeds things up. It's a noticable speed increase on all my systems. It may not like your super-old hardware, though, if it is, indeed, super-old.
