KDE Performance Boost Ahead
Ostatic ^ | August 30th | Susan Linton

Posted on 09/14/2011 4:58:52 AM PDT by Halfmanhalfamazing

Have you experienced performance issues when using KDE? If so, then you aren't the only one. While things have been improving as KDE 4 matures, some users still have registered complaints. And one KDE hacker is trying to address them.

Martin Gräßlin had begun working towards "rendering at 60 frames" per second. Gräßlin stated in a blog post today, "I could not imagine how a frame could take longer to render than the 16.67 msec." But after some thought he realized where a couple of bottlenecks may be hiding.

In testing the effect chain performance, Gräßlin discovered a bug that was slowing down the works. This will be fixed in 4.7.2. He states this will improve performance quite a bit.

But a significant improvement will come in 4.8. One of the ideas he's been mulling over for a while involves the way the repaint loop draws the windows. In normal operation the effect chain calls on each effect process to repaint the interface according to what the user or the desktop is doing. Many times, this is little or nothing but each effect is repainted. This is where Gräßlin thought some time could be saved.

I guess technology is passing me by. I really liked KDE 3, but the new plasma push leaves me a bit cold. I like my programs in an organized menu, rather than littered all over the desktop in panes.

Not sure if this is a performance “boost” or just fixing performance lag to catch up with the others.

I installed and ran KDE4 on top of Ubuntu 11.04 for a week. It was a painful experience. To be fair, Gnome 3 was nearly as painful.

It seems the upward trend parallels Win98, WinXP, Win7, ...i.e. MORE resources consumed. Much more. And, of course, they are all trying to look like a Mac, too. That fly’s in the face of the Linux/Ubuntu philosophy.

Unity? Oh, techie, please! Are you serious? Really? That’s it?
I’ll keep my Mint9, for it’s simple elegance and function, and my Ultimate Edition for brutish and blingy, all encompassing abilities to accomplish ANYTHING, right out of the box!

P.S. Desktops are NOT itty bitty teeny tiny Tablets that we operate with our fat fingers. Give us our Danged MENUS! lol

I would love to be able to run a Linux desktop on my home computer, but until it's as easy to run as Windows is I just can't go it. Point, double click, and the program is installed. You still can't do that with Linux. Plus most programs out there only run on a Windows desktop.

Sorry gang, but until Linux can emulate the Windows desktop better I'm stuck.......

Linux installs software much easier than Windows does, and has done so for several years.

Easier, faster, safer. The naysayers are years behind the times.

There’s no naysaying. Programs like synaptic have been around for ages now. They’ve been around so long, that they’re being eclipsed by other programs such as Kpackagekit.

The days of the linux command line are over. The only time anyone needs a command line in linux parallel when someone needs one in Mac OS or even Windows. For troubleshooting purposes.

Arguably, installations in linux are easier due to the repository. I can install every program I need in one shot. You need multiple disks, multiple licence codes.

Here's the output of glxgears in the initial window, and full screen(1280x1024)

KDE 4.6.5 on Fedora 14

Video: NVIDIA GeForce GT 240/PCI/SSE2

I'm using the NVIDIA drivers

25475 frames in 5.0 seconds = 5094.886 FPS
26175 frames in 5.0 seconds = 5233.910 FPS
26374 frames in 5.0 seconds = 5274.770 FPS
26354 frames in 5.0 seconds = 5270.770 FPS
26243 frames in 5.0 seconds = 5248.497 FPS
26256 frames in 5.0 seconds = 5251.155 FPS
9037 frames in 5.0 seconds = 1807.123 FPS
3930 frames in 5.0 seconds = 785.885 FPS
3941 frames in 5.0 seconds = 788.098 FPS
3938 frames in 5.0 seconds = 787.504 FPS
3952 frames in 5.0 seconds = 790.120 FPS
3925 frames in 5.0 seconds = 784.633 FPS

I've gotten better results on the same box in the past, but for me, this isn't bad.

Not from what I see. It doesn’t emulate the Windows desktop well enough, and you can’t load programs the same way.

” Point, double click, and the program is installed.”

Yep. Viruses and malware are a snap to install.

Linux is NOT Windows. It doesn't act the same, and it doesn't do things the same way.

It is not a windows replacement.
