OS Speed Differences?


Ok, this is to settle an argument. How many people here say there is a speed difference between different operating systems?

I say there is a speed difference, he is trying to claim that the only difference is how much memory they use. I'm also not just talking between windows and linux, I'm talking also between windows 98 and windows XP, etc.

So how many of you say there is a speed difference, and how many think its just memory? I've shown this guy facts before, but he won't listen to me.

hum? I don't exactly understand your question. How you define speed? Anyways speed is not a reason why one OS is faster than another. It's indeed mainly how the memory is being used and stored... What do you think then that is the reason of differences?

It is slightly more complicated then just how much RAM you have.

Process management is a big deal performance wise. The kernel that does processor scheduling that minimizes CPU pipeline flushes the best while keeping the CPU full of useful data will have a positive gain to the speed of the overall system.

Memory management: There is way more to this then just how much RAM you have. How efficiently the OS uses the RAM is a big deal. You want to limit the amount of reads and writes to RAM as much as possible because it is significantly slower then cache on the processor. As a result you want to be able to figure out how to get the most out of each read and write and how to try and get data from memory to cache before it is actually needed by the process.

Disk I/O is another big issue. Hard drives are easily the slowest thing on your computer today. Getting data off the hard drive takes a terribly long time in comparison with RAM or cache. As a result you want to implement a disk I/O system that minimizes the amount of reads and writes to disk. Believe it or not, having a good file system really does make your overall OS responsiveness increase.

like he said above pluss, what it can suport (this realy only makes the loading tiem longer and not realy impact performance once its all started), teh gui is another imprtoant part, IE, the linux terminal is faster then the frambuffer withch is faster then the xfree86 and wm stuff) so much of the system performance is cuse of the gui used, and less on teh kernel (asuming the kernel is made to be at elast ok)

You are misunderstanding, I'm not asking all the things that effect OS speed. What I'm saying is, there are more things than just memory usage that effect speed - such as visualizatios, mathematical calculations done by the OS, special daemons running that use CPU cycles, that sort of thing.
