The graphs below represent a performance comparison
between Mac OS versions 7.6, and 8.0. Test were performed
on a Performa 6300. These are real world "stopwatch"
tests as described below. OS 8 scores reflect the percentage
of time relative to 7.6 which receives a score of 100%. In
the first example below Version 8 took 30% the amount of time
to perform the task that it took version 7.6. They confirm
what is obvious to the casual observer, that system 8 is a
dramatic improvement in speed over it's predecessor. OS 8
is optimized for the PowerPC processor and you will no doubt
not see this kind of improvement in 040 processor machines.
For the test below 3 folders totalling 11.5MB
in size and containing 446 files were duplicated
For the test below 3 folders totalling 11.5MB in size and
containing 446 files were deleted from the trash
In the test below 12 windows containing 1,100
files were opened at once and the time elapse till the last
window had displayed was recorded. As you can see there is
not a great difference but it is the one test in which there
was a slight decrease in performance. There have been some
observations that windows are MUCH SLOWER to draw. I do not
believe this to be the case, but windows may appear to draw
more slowly because there appears to be a change in the way
windows are opened. In the past information about the window
was being calculated before the window opened (you could see
the little stopwatch moving round before the window opened
for folders with many files) Under system 8 the window opens
immediately and calculation comes next so there is more a
perception of slowness than a reality.
Reboot times with System extensions only are compared in
