When playing around I also noticed the size of the profiles is quite different (<1K for Eye-One Match, 4K for ArgyllCMS). Guess that is a result of specifying a high number of patches...

I'm pretty sure the i1Match software produces a matrix/shaper profile for displays, where Argyll will by default produce a medium sized CLUT based profile. My understanding is that the CLUT profile is more accurate (much more if you use enough swatches) but considerably larger and slower than a matrix/shaper profile.

I've certainly noticed that if I use an Argyll-generated profile (without forcing production of a matrix/shaper profile) then apps like Firefox 3.0 (with colour management enabled) are considerably slower than they are with the i1Match matrix/shaper profile. The results seem to be very nice with Argyll's profile, though, very smooth and even despite the fact that my laptop's display is miles from the target D65 whitepoint and needs heavy LUT-based adjustment.
I tried loading the EyeOne profile with dispwin, but that did not work. What is the quickest way to load the profile (actually the LUT parts) of non Argyll generated pofiles?
i1Match comes with a profile loader application. It'll be in the Startup directory of your Start menu unless you removed/disabled it.
