Maybe it was already suggested but it might be prudent to make a test in PTS which runs two or more different programs at the same time in order to attempt to benchmark any noticeable improvements that each scheduler may provide. These need to of course be separated out enough so that they don't fall victim to the scheduler lumping them together, and of course one should stress I/O and the other, say, audio or graphics or something like that.
I'm sure readers would be interested in such a project in response to this scheduler.
I.e., does it really work, and is it really better? Tests will help determine that.
Ah, the scientific method...

I was just thinking about FreeBSD, back in 1999 I was using 4.3. The file operations were slow but the system response was quick.
Everything felt double buffered.

I'm testing things myself.
I have:
Gigabyte GA-MA785GM-US2H
AMD SEMPRON 140 UNLOCKED to an AMD Athlon(tm) II X2 4400e
1024 Megabytes of ram (initially)
128 Megabytes shared onboard ATI 4200HD Video Chipset
160 Gigabyte Western Digital IDE hard-drive (Walmart discount)
DVD/Burner IDE (Walmart discount)
Ubuntu 9.10 Karmic Koo'lala 64bit latest updates 2.6.31-20 kernel.
Essentially there is only one IDE connector on this motherboard so the bandwidth is shared.
I had the sluggish response with copying files to and from the hard-drive. What really hit performance was copying from the DVD-Rom.
I suspect it's the IDE port. I've encountered this in the past and used a raid controller / IO card to hook up the hard-drive which alleviated the IO problems somewhat.
Today I installed 4 Gigabytes of memory and the performance magically picked up. The user interface, Gnome has improved when copying a large amount of files. I'm using my Wine directory which is full of ISO and huge files as copying test.
I know the Intel guy just mentioned the VM and I truly believe he is correct. There are some major performance issues with the VM after 2.6.24.
I'm going to make SVG's myself.

Originally posted by squirrl View PostI've seen the behavior in Windows 7 64bit. In fact I am starting to believe that 64bit is plagued with problems. I speculate that developers just don't understand how to problem for 64bit yet. Perhaps it could even be just the AMD processors. I unlocked an extra core on my processor. I noticed the system was more responsive when I kept the core locked (Windows / Linux) in the 64bit environment.
1. Has anyone with IA64 had any problems?
2. If you have AMD64, have you unlocked a locked core?
3. Sun and DEC have had 64bit operating systems for years. Anyone with experience under those environments got any input?
