- This repost is to clerar up a typo, speed to do recalc was 3.5 seconds not
- 2.5 seconds, sorry

- I tried it using excel 3 on a IIci, cache card, two screens run in 8
- bit(640x480) and 4 bit (15" stardard number of pixels) modes with video cards
- (non-accelerated), system 7.01+, 20 meg ram, 3meg excel partition.
-
- recalc took 2.5(correction 3.5) secs (hand held, so, say give or take 0.2
- seconds), looks
- like Evan may be correct 4.0 may be a little slower than 3.0. Looks like
- Iskandar Taib is suffering from the onboard video slow down on the IIci or
- maby the lack of a cache card.

- I have previously run a simular test using a more complex calculation wich is
- to messy to state clearly here but it involved multiplications, additions,
- divisions, sins, cosins, averages, standard deviations, roots, powers etc.,
- more or less at random, (care was taken to use absoulte values in some places
- to eliminate (divide by zeros, negative roots) etc.) all based on other cell
- results so that changing cell 1A would cause a complete recalc as in the
- above exapmle. I also measured the time to scroll the 1000 row spread sheet.
- Results as follows
-
- Mac II, 16mHz, system 7.01+, 8bit 640 x 480 video, 8 meg ram
- Mac IIci, 25mHz, see above
- 386dx, 33mhz system, windows, 3.0, 640x480 svga screen, no cache. 8meg RAM
- calc.(sec) scroll(min:sec)
- Mac II 35.3 2:16.2
- Mac IIci 15.3 1:31.2
- Mac IIci/cache off 19.2 1:44.7
- 386dx 22.5 2:25.3
-
- Sorry about lack of spec for the 386 system, but I couldn't find the manuals
- for it, or the purchase orders, but its was a typical clone package with a 1
- meg video card and 14" hi-res monitor, AT style slots. The 386 on this calc
- seem to be in line with the Mac IIci/cache off, however the scroll
- performance was fairly slow.
-
- just my $0.02, this was my playing and doesn't reflect any official position
- or recommendation by NASA or the US Government.
