The ~200 Line Linux Kernel Patch That Does Wonders
Is there a way to objectively measure desktop/mouse responsiveness?
You could use a high-speed camera (~1000fps) to measure the frames between a mouse-click and the reaction of the desktop (changing the button).
This patch has all the hype but how do you quantify the improvement?
Do the steps mentioned in the article :
Compile a kernel with "make -j64" and start Firefox and a HD-video. Without the patch the system gets totally sluggish. With the patch you can watch the video and use Firefox without any bigger problems.
Haha, that reminds me when I was with my dad when he bought a new computer; PC_store_owner: "Hello. How can I help you?" Dad: "I'm in the market for a new computer." PC_store_owner: "Well we have bla bla bla" Dad: "Just give me the best of the best computer you have" PC_store_owner: "OK, the best computer we have here has x, y, z and a ten megabyte harddisk." Dad: "Ten megabytes, is this the best of the best?" PC_store_onwer: "Sir, ten... megabyte. You'll never get to fill it up".
10 megabyte cool , but you should have told your dad to get the AMIGA 1000/500 + A590 20Meg XT/SCSI drive 50 pin internal SCSI header
internal 40 pin XT IDE header (8 bit only) http://amiga.resource.cx/exp/a590 http://en.wikipedia.org/wiki/Amiga
and you could have used Real responsive round robin Multitasking microkernel OS while using LightWave 3D etc..
the User responsiveness of the official AT&T SVR4 Amiga port , Amix one of only a few that got official UNIX sanction, (QSL QNX , you know the one before RTP6, the RIM OS now,being another), wasn't to shabby eather.
Well at the time 640K really was enough for anybody.
No it wasn't, and only a little later, people where putting 2 meg of fast ram in their A590's etc, and using it to it's fullest to make nice 3D Amiga gen-locked transitions for Video Toaster on their Ami's.
Besides, this is NOT about multitasking, it's about responsiveness. An entirely different thing
Dude every kernel can multitask. Windows Vista/7/NT6 multitasks primarily by use of mouse focus... Yeah that's right. Check the interview of the Vista kernels devs on Channel9; http://channel9.msdn.com/
Maybe I should have said load balancing, although Linux is currently fscking that up in the disk I/O department...
If you want responsiveness (I'm guessing UI?) then check out E17.
just tried the liquorix kernel on lucid. boy am i glad that i found the backup of my menu.lst.
i will now join the ranks of those nagging for a ppa or at least an ubuntu walkthrough. this patch is way too good to wait for the next distribution to pick it up. just do it for fame.
