I tried installing LXDE to a fresh Ubuntu 10.04 installation and it really is A LOT faster. Group scheduling goes from “useful for some specific server loads” to “that’s a killer feature”.Ĭan’t wait for this to become default in every linux distro.ītw. So I think this is firmly one of those “real improvement” patches. But there’s clearly enough of a CPU load when loading a new web page that if you have a load average of 50+ at the same time, you will be starved for CPU in the loading process, and probably won’t get all the http requests out quickly enough. Maybe it shouldn’t have been surprising, but I always associated that with network performance. It’s an improvement for things like smooth scrolling around, but what I found more interesting was how it seems to really make web pages load a lot faster. Admittedly, my “testcase” is really trivial (reading email in a web-browser, scrolling around a bit, while doing a “make -j64” on the kernel at the same time), but it’s a test-case that is very relevant for me. I’m also very happy with just what it does to interactive performance.
#Linux renoise Patch
And I have to say that I’m (very happily) surprised by just how small that patch really ends up being, and how it’s not intrusive or ugly either. Look what Linus Torvalds told about the patch:
There’s a new patch that really improves linux kernel peformance on desktop. KDE uses kwin which proved to peform better.įor me, running openbox and setting 3 periods did the trick. XFCE uses xfwm4 which is horrible as well. Gnome uses metacity or compiz if you have desktop effects enabled. What else changed between these Desktop environment answer: THE WINDOW MANAGER.
#Linux renoise driver
So, the module driver is the same, alsa, jack, renoise, all the same. Installed lxde, even lighter than xfce, uses gtk as well. Result? CHOPPY SOUND! Messing with windows? HORRIBLE CHOPPY SOUNDS! To test if that’s true, I installed XFCE, which uses GTK and it’s lighter than both gnome and KDE. it’s the same driver loaded, a heavier Desktop environment, and its all good. So, how is that possible, I asked to myself.
#Linux renoise windows
Openning other programs and shaking windows gives me little xruns.
#Linux renoise install
Then, one day I try and install KDE which is known for beeing more resource hungry than gnome, I run renoise and it peforms waaaaaaaaaaaay better! I do that trick to increase the period to 3 and that’s it, perfect. If I even think of doing this on gnome I get a xrun. Curious enough, I can even agressivly open lots of programs, shake the windows all at the same time and no sound interruption on Windows. So what I think? Maybe its the driver right? The Windows one is good, the linux one is crappy. I didn’t even had to set realtime options in pam.ĭual boot system, linux sucks, Windows works perfectly. You can also choose Gnome/openbox at the login screen. Play a heavy music and see if the sound goes ok. Run renoise, go to soundcard options in renoise and increase periods to 3.
Logout from gnome, at the graphical login screen, select the user you want to login, type your password, but before you hit enter to login, check the botton of this screen, theres a menu to select the desktop environment. What does the window mnager has to do with sound chopping?: it steals system resources, even worst for us with crappy soundcards. Metacity sucks too?: Yes it sucks big time. Which one peformed worst? Gnome because it uses compiz, or metacity if you disable desktop effects. Which one peformed best?: lxde because it uses openbox as window manager. How I came to that conclusion: Installed KDE, XFCE, LXDE and tested renoise with “DemoSong - soon soon” and openned lots of programs, shaked windows, to see if interrupts ocurred.
Problem: Sound getting interrupted (xruns) Soundcard: my laptop has one of those onboard High Definition Audio soundcards.
