I'm sorry, but the lack of answers in this thread suggests that the problems you experience are not common.
AC11 is better optimised for MacIntel than AC10, so I'd suggest an upgrade if you use that.
The FBDIMM 'latency penalty' mentioned regarding the MacPro's is problably not the culprit. It could diminish the performance of some processes by single-figure percentages, but not cause spinning beachballs to the extent you mention.
There may be other suggestions, but I guess you've already done a search in this forum. All I can come up with is general advice:
- check that you've applied Apple's latest system updates (10.4.xx).
- check that you don't have unnecessary background processes running. For example, a new Mac with a lot of data on the hard disks spends time for Spotlight indexing. Also, if you often connect/disconnect external drives, exclude them from indexing with Spotlight's system settings.
- Check that you have enough free space on the internal start-up hard drive. I'd recommend at least 20% free.
- Optimise your system (clean caches, update system databases etc) regular, for example using a third-party free utility program like OnyX
http://www.titanium.free.fr/pgs2/english/download.html (do NOT use the betas). There is an 'Automate' option in Onyx that is quite convenient.
- Use a font manager (I recommend Linotype's free FontexplorerX
http://www.linotype.com/fontexplorerX ) to trim your system from unneeded fonts. Just Apple's system fonts and the ones you frequently use should be active.
- In Archicad, check that you don' t have excessive libraries loaded, and that the default (AC11's delivered and if you need to use AC10 files, the AC10 subset library) libraries are installed with Archicad on the local workstation. Only office libraries that frequently change should be loaded from a network server.
- If you've done all of the above, and Archicad still is slow, re-install Archicad, carefully checking the right options.
- When Graphisoft tells us it's safe (they will in this forum), upgrade your machines to Leopard. It's better optimised for Intel and may help.
