Hi, everyone.
I did some short test to compare the cpu usage on a few computers running dos software and did not make any chart, just made note of some general observations.
The dos software i used for this test is not very cpu friendly when it comes to being run under windows nt. The dos software is used all day long on workstations and there are some programs that are run to help hold down the cpu usage of these programs while they area being run. This is a very common situation in dos software, where the cpu usage is keep very high, and most of the cpu usage comes while waiting for a keyboard input in a console windows and i want you to know we do not run any dos graphic's software. it is all just plain text on a console screen.
well just to make things short, i had to replace a broken computer with a newer one and i picked a dual processors made by intel. it is rated at 1.8 Ghz and i use the windows 2000 pro operating system.
so far, i have been impressed by the speed of the machine compared to other 3.2Ghz machines. I am sure the new computer has faster ram, more cpu cache, and some other internal parts that are speeder than the previous 3.2Ghz machine.
i have several other machines which i did the same test on, that was just running the dos software on its own from the command prompt and watching the cpu usage inside the task manager.
the w2k os can use up to two processors and what knowledge i have picked up over the years, is that w2k will do some of its internal processing on the second processor if it finds one there when the os is installed. I think just about all or at least mostly all our software is not written to take advantage io using the second processor.
the outcome of what i saw, was there was a dramatic reduction in cpu usage compared to the other computers, which where not dual processors.
I do not consider hyper-processors to be dual processors and where we have these type of processors in computers, i have turned that feature off in the bios, because i believe for what we are running, because it just makes the computer slower when programs are not going to use a second processor.
so without any other test at this time, it appears that if you are going to be running any dos cpu hungry programs, a dual processor maybe what you should considering when purchasing equipment.
it would be nice to hear from some of the other members if they are seeing what i am seeing and that is a big reduction in cpu usage on dual processors while running dos software.
even software written to run on a 32bit system could have these same results in poor cpu usage, but i would think most programmers writing code for the newer os(windows nt and up) have addressed this issue for any software that stays running for long periods of time.
i am sure i will be doing a little more testing in this area, but do not plan on anything scientific.
