I am going to do some more speculating on the 1 millisecond default polling value of the USB drive [ not the cd drive which I accidently wrote in my previous posting ] and its effect on the xp operating system processing speed.
Dividing the "system bus speed" by a factor of a 1000 would only apply for a worst case scenario: that is , if the computer engineers were to deliberately design the 1 millisecond polling output to Shut DOWN the complete "system bus " every millisecond when the polling circuit is turned on by the microprocessor [assuming that the polling circuit is not a separate free running oscillator running at a 1000 cycles per second - astable as opposed to monostable - a lack of synchronizing would no doubt cause to many problems , so the polling is no doubt tripped off by the microprocessor].
Even if "the total shut down "design is not opted for by the computer engineers - they could still opt to have the 1 millisecond polling increments shut down SOME of the "system bus" that is, some of the 32 bit address or 64 bit address space.
If the computer designers chose not to shut down any EXTRA parts of the system bus every millisecond and just let the 1 millisecond polling increments utilize the required amount of system bus address space it required in order to poll the USB drive --- I wonder how many BYTES per second or BYTES per millisecond of computer band width would be taken by the polling ciruit?How much system address space has to be set aside every second to process the 1 millisecond polling increments ?
I suppose that the polling ciruit has its own coded file.How large is it? Would it be a couple of thousand bytes in size or would a file the size of a couple of hundred bytes be enough to get the USB polled?
I assume that you could Multiply the Size of the Polling File by a Factor of 1000 in order to find out how many Bytes per second that the computer has to continually process.
