Improving Linux Kernel Performance
developerWorks writes "The first step in improving Linux performance is quantifying it, but how exactly do you quantify performance for Linux or for comparable systems? In this article, members of the IBM Linux Technology Center share their expertise as they describe how they ran several benchmark tests on the Linux 2.4 and 2.5 kernels late last year. The benchmarks provide coverage for a diverse set of workloads, including Web serving, database, and file serving. In addition, we show the various components of the kernel (disk I/O subsystem, for example) that are stressed by each benchmark."

Note to moderators: I know you have a duty to mod this down. However, please be reasonable. This is offtopic. Not a troll. A troll trys to piss people off, whilst I only wish to share my art.
Scene 3: Radio Shack
Calculator Man:This is the fourth Radio Shack to be broken into this week, not to mention a recent rash of calculator thefts. What could Science Boy be up to?
Owner: Calculator Man, it looks like everything is here except for 25 128K * 8 RAM chips.
Calculator Man: RAM chips! What would Science Boy want with RAM chips? He only has a Ti-86. He can't upgrade the RAM on it. It isn't expandable.
Scene 4: 14.817 levels below ground, 44 Tremont Dr.
Science Boy:Fools, all of them. Calculator Man thinks I'm stuck with a Ti-86, but I'm not burdened by that plastic piece of trash. I have THE HP48GX, Ha Ha...Now I can expand the memory to whatever I want to, and can implement my devious plan.
Evil Henchmen 2:Here you are, sir, 7582 128K * 8 RAM chips all wired into this RAM card, and 10347 into that one. (I know what you are going to say. Don't.) The wires all lead to the backpack which houses the chips.
Science Boy:Beautiful, absolutely beautiful. The ultimate RAM expansion cards for the ULTIMATE CALCULATOR, Ha Ha Ha. And now, to download the ultimate artificial intelligence program from my computer to the HP. (clicks on a button)
Computer Screen:Download in progress. Time Remaining: 8.36 years. Have a nice day.
Science Boy:That might be a little hitch in my planning. I knew I should have used XModem instead of Kermit.
8.42 years later
Science Boy:Those computer estimated times never tell the truth. At last, the program has downloaded. Now to run it...(presses ON)
Calculator:What the hell is this?
Science Boy:It's alive!!
Calculator:It? It? Scuse me, my name is not it. From now on, I'm Bob to you, got it?
Science Boy:What's with the attitude, Bob?
Calculator:Hey, you stupid author, Bob goes for you too.
Bob:Look, you were born in a couple of minutes. I was born in 8.42 years. That's enough to get anybody pissed.
Science Boy:Well, I'm sorry about that. You wanna be my lab partner?
Bob:Why the hell would someone as intelligent as me want to work with a stupid human like you?
Science Boy:Hey, I wrote you. Besides, what is up with the filthy vocabulary?
Bob:CRC screwed up and didn't catch a faulty vocabulary packet. Hello was abbreviated to hell. Fortunately, unlike my creator, I have a brain, and caught the error. Still, I happen to like the word hell.
Science Boy:You hurt my feelings. Listen up, Bob, you keep on like this, and I will purge you from the RAM.
Bob: From all 17930 RAM chips? Fat chance.
Science Boy: I will too. You just watch.
Bob: No you won't. (Starts beeping insanely. All of a sudden, a bright flash appears from the IR port, and Science Boy falls to the ground)
Science Boy: No, my son, cough, hack, how could you. I created you. How could you do this to me?
Bob: So long, pops. Ha Ha Ha (evil calculator type laugh)
Science Boy: Cough, hack, what have I done? I've created a monster. (Dies)
Bob: And now, to get rid of that pesky Calculator Man, and to make all the Ti's of the world slaves to all the HP's.
Is this the end of Calculator Man. Will all of the Ti's become slaves of the HP's? What will become of Bob? Find out in the next wonderful episode of The Adventures of Calculator Man.
You know what. Screw it. I'm tired. You all know what is gonna happen. What chance does Calculator Man have against any HP, let alone a souped up one like this baby. Besides, It's not like the Ti's aren't the slaves of the HP's anyway. Bob is gonna kick everybody's butt, and take over the world. I don't believe in none of that happy ending stuff. Go Bob.
Thats how fast I managed to get in tux racer. Fast enough for you?
Gonna mod me down? Fuck you then.
.committing high treason, etc....
